[Abstract] [DOI] [pdf]
For the synthesis of spherical Au nanoparticles (NPs), Turkevich method is very popular. However, in this method the citrate reduction of gold is carried out at high temperature, which is often a draw back. Herein, we describe a near room-temperature synthesis of cetyltrimethylammonium bromide (CTAB) stabilized spherical Au NPs of various sizes in a novel one-step synthesis protocol. We show that, in a growth solution containing CTAB, HAuCl4 and ascorbic acid, nucleation can be induced by the addition of AgNO3. This allowed us to eliminate the necessity of the presence of seed particles for NP growth. We show that NP size is strongly influenced by the CTAB to Ag molar ratio in the reaction medium. By tuning the CTAB to Ag molar ratio the sizes of the NPs can be tuned from 8 to 64 nm. Owing to the ease of synthesis and superior properties, CTAB stabilized NPs can replace the conventional citrate capped NPs for many applications.

[Abstract] [DOI] [pdf]
We report on the temperature dependence of the spin-pumping effect and the Gilbert damping in Co/Pt bilayers grown on Silicon oxide by measuring the change of the linewidth in a ferromagnetic resonance (FMR) experiment. By varying the Co thickness ${{d}_{\text{Co}}}$ between 1.5 nm and 50 nm we find that the damping increases inversely proportional to ${{d}_{\text{Co}}}$ at all temperatures between 300 K and 5 K, showing that the spin pumping effect does not depend on temperature. We also find that the linewidth increases with decreasing temperature for all thicknesses down to about 30 K, before leveling off to a constant, or even decreasing again. This behavior is similar to what is found in bulk ferromagnets, leading to the conclusion that in thin films a conductivity-like damping mechanism is present similar to what is known in crystals.

[Abstract] [DOI] [pdf]
Explicit dependencies of the local density of states and the magnetization local density of states have been obtained around magnetic point defects in a two-dimensional electron gas with Rashba spin-orbit interaction . The expressions are given in the Born approximation for arbitrary magnitude and orientation of the defect magnetic moment, and for arbitrary size of the constant of spin-orbit interaction alpha/. On the basis of our asymptotically exact formulas a procedure for the determination of the constant alpha/ in STM experiments is proposed. The novel analytical results are compared with the numerical and approximate results of previous work. At variance with earlier work we find that that magnetic scattering in the presence of spin-orbit interaction does not modify the local density of states and that the spin texture resulting from in-plain orientation of the defect magnetic moment, and elastic scattering, is not a purely in-plane spin texture.

[Abstract] [DOI] [pdf]
This experimental work aims at probing current-induced forces at the atomic scale. Specifically it addresses predictions in recent work regarding the appearance of run-away modes as a result of a combined effect of the non-conservative wind force and a ‘Berry force’. The systems we consider here are atomic chains of Au and Pt atoms, for which we investigate the distribution of break down voltage values. We observe two distinct modes of breaking for Au atomic chains. The breaking at high voltage appears to behave as expected for regular break down by thermal excitation due to Joule heating. However, there is a low-voltage breaking mode that has characteristics expected for the mechanism of current-induced forces. Although a full comparison would require more detailed information on the individual atomic configurations, the systems we consider are very similar to those considered in recent model calculations and the comparison between experiment and theory is very encouraging for the interpretation we propose.

[Abstract] [DOI] [pdf]
One dimensional systems strongly enhance the quantum character of electron transport. Such systems can be realized in 5d transition metals Au, Pt, and Ir, in the form of suspended monatomic chains between bulk leads. Atomic chains between ferromagnetic leads would open up many perspectives in the context of spin-dependent transport and spintronics, but the evidence suggests that for pure metals only the mentioned three 5d metals are susceptible to chain formation. It has been argued that the stability of atomic chains made up from ferromagnetic metals is compromised by the same exchange interaction that produces the local moments. Here we demonstrate that magnetic atomic chains can be induced to form in break junctions under the influence of light molecules. Explicitly, we find deuterium assisted chain formation in the 3d ferromagnetic transition metals Fe and Ni. Chain lengths up to eight atoms are formed upon stretching the ferromagnetic atomic contact in deuterium atmosphere at cryogenic temperatures. From differential conductance spectra vibronic states of D2 can be identified, confirming the presence of deuterium in the atomic chains. Shot noise spectroscopy indicates the presence of weakly spin polarized transmission channels.

[Abstract] [DOI] [pdf]
The formation and rupture of atomic-sized contacts is modelled by means of molecular dynamics simulations. Such nano-contacts are realized in scanning tunnelling microscope and mechanically controlled break junction experiments. These instruments routinely measure the conductance across the nano-sized electrodes as they are brought into contact and separated, permitting conductance traces to be recorded that are plots of conductance versus the distance between the electrodes. One interesting feature of the conductance traces is that for some metals and geometric configurations a jump in the value of the conductance is observed right before contact between the electrodes, a phenomenon known as jump-to-contact. This paper considers, from a computational point of view, the dynamics of contact between two gold nano-electrodes. Repeated indentation of the two surfaces on each other is performed in two crystallographic orientations of face-centred cubic gold, namely (001) and (111). Ultimately, the intention is to identify the structures at the atomic level at the moment of first contact between the surfaces, since the value of the conductance is related to the minimum cross-section in the contact region. Conductance values obtained in this way are determined using first principles electronic transport calculations, with atomic configurations taken from the molecular dynamics simulations serving as input structures.

[Abstract] [DOI] [pdf]
We report a seedless protocol based on the oriented attachment of nanoparticles for the synthesis of Au nanoworms (NWs). NWs are grown by reducing HAuCl4 with ascorbic acid (AA) in high pH reaction medium and in the presence of growth directional agents, cetyltrimethylammonium bromide (CTAB) and AgNO3. Although we have used the same reducing and growth directional agents as typically used for the synthesis of Au nanorods, the growth mechanism of NWs is markedly different from that of nanorods. Instead of the anisotropic growth of seed particles, the NWs grow through oriented attachment of nanoparticles. By varying different reaction parameters we have seen that the length of NWs can be controlled from tens of nanometers to a micrometer. Furthermore, the aspect ratio (AR) can be tuned from 2 to 30. This is almost the whole range of AR and length for Au nanorods so far achieved with seed-mediated multiple step synthesis protocols.

[Abstract] [DOI] [pdf]
We describe the synthesis of PZT nanoparticles using a hydrothermal method. We demonstrate that the morphology of the PZT nanoparticles can be controlled by tuning the concentration of the mineraliser, KOH. The experimental results show that for low concentrations of KOH (2 M) the reaction kinetics favor a high yield of spherical particles with an average diameter of 5.3 mm. However, higher concentrations of KOH lead to the formation of branched nanostructures containing up to 8 mm long nanorods. TEM and XRD investigations provide evidence that the branches are single crystalline. The influence of KOH concentration on polymer induced particle formation is discussed.

[Abstract] [DOI] [pdf]
We have grown epitaxial Sm-Co thin films by sputter deposition from a single alloy target with a nominal SmCo5 composition on Cr(100)-buffered MgO(100) single-crystal substrates. By varying the Ar gas pressure, we can change the composition of the film from a SmCo5-like to a Sm2Co7-like phase. The composition, crystal structure, morphology, and magnetic properties of these films have been determined using Rutherford Backscattering, X-ray diffraction, and magnetization measurements. We find that we can grow films with, at room temperature, coercive fields as high as 3.3 T, but with a remanent magnetization which is lower than can be expected from the texturing. This appears to be due to the Sm content of the films, which is higher than expected from the content of the target, even at the lowest possible sputtering pressures. Moreover, we find relatively large variations of film properties using targets of nominally the same composition. At low temperatures, the coercive fields increase, as expected for these hard magnets, but in the magnetization, we observe a strong background signal from the paramagnetic impurities in the MgO substrates.

[Abstract] [DOI] [pdf]
Pt is known to show spontaneous formation of monatomic chains upon breaking a metallic contact. From model calculations, these chains are expected to be spin polarized. However, direct experimental evidence for or against magnetism is lacking. Here, we investigate shot noise as a potential source of information on the magnetic state of Pt atomic chains. We observe a remarkable structure in the distribution of measured shot-noise levels, where the data appear to be confined to the region of nonmagnetic states. While this suggests a nonmagnetic ground state for the Pt atomic chains, from calculations we find that the magnetism in Pt chains is due to “actor” electron channels, which contribute very little to ballistic conductance and noise. On the other hand, there are weakly polarized “spectator” channels, which carry most of the current and are only slightly modified by the magnetic state.

[Abstract] [DOI] [pdf]
The controlled patterning of anisotropic gold nanoparticles is of crucial importance for many applications related to their optical properties. In this paper, we report that gold nanorods prepared by a seed-mediated synthesis protocol (without any further functionalization) can be selectively deposited on hydrophilic parts of hydrophobic–hydrophilic contrast patterned substrates. We have seen that, when nanorods with lengths much smaller than the width of the hydrophilic stripe are used, they disperse on these stripes with random orientation and tunable uniform particle separation. However, for nanorods having lengths comparable to the width of the hydrophilic stripes, confinement-induced alignment occurs. We observe that different interactions governing the assembly forces can be modulated by controlling the concentration of assembling nanorods and the width of the hydrophilic stripes, leading to markedly different degrees of alignment. Our strategy can be replicated for other anisotropic nanoparticles to produce well-controlled patterning of these nanoentities on surfaces.

[Abstract] [DOI] [pdf]
We present a theoretical analysis of the standing wave patterns in scanning tunneling microscope (STM) images, which occur around surface point defects. We consider arbitrary dispersion relations for the surface states and calculate the conductance for a system containing a small-size tunnel contact and a surface impurity. We find rigorous theoretical relations between the interference patterns in the real-space STM images, their Fourier transforms and the Fermi contours of two-dimensional electrons. We propose a new method for reconstructing Fermi contours of surface electron states, directly from the realspace STM images around isolated surface defects.

[Abstract] [DOI] [pdf]
We have found an asymptotically exact solution of the Schrödinger equation for electrons tunneling into surface states through an inhomogeneous barrier of large amplitude. Assuming an elliptic dispersion law for the charge carriers the “standing wave” pattern in the conductance of the system resulting from the electron scattering by a single defect in the vicinity of the surface is analyzed.

[Abstract] [DOI] [pdf]
Igor Yanson showed 38 years ago for the first time a point-contact measurement where he probed the energy resolved spectroscopy of the electronic scattering inside the metal. Since this first measurement, the pointcontact spectroscopy (PCS) technique improved enormously. The application of the scanning probe microscopy (SPM) techniques in the late 1980s allowed achieving contacts with a diameter of a single atom. With the introduction of the mechanically controlled break junction technique, even spectroscopy on freely suspended chains of atoms could be performed. In this paper, we briefly review the current developments of PCS and show recent experiments in advanced scanning PCS based on SPM techniques. We describe some results obtained with both needle-anvil type of point contacts and scanning tunneling microscopy (STM). We also show our first attempt to lift up with a STM a chain of single gold atoms from a Au(110) surface.

[Abstract] [DOI] [pdf]
Metal/organic interfaces critically determine the characteristics of molecular electronic devices, because they influence the arrangement of the orbital levels that participate in charge transport. Studies on self-assembled monolayers show molecule-dependent energy-level shifts as well as transport-gap renormalization, two effects that suggest that electricfield polarization in the metal substrate induced by the formation of image charges plays a key role in the alignment of the molecular energy levels with respect to the metal’s Fermi energy. Here, we provide direct experimental evidence for an electrode-induced gap renormalization in single-molecule junctions. We study charge transport through single porphyrintype molecules using electrically gateable break junctions. In this set-up, the position of the occupied and unoccupied molecular energy levels can be followed in situ under simultaneous mechanical control. When increasing the electrode separation by just a few a˚ngstro¨ms, we observe a substantial increase in the transport gap and level shifts as high as several hundreds of meV. Analysis of this large and tunable gap renormalization based on atomic charges obtained from density functional theory confirms and clarifies the dominant role of image-charge effects in single-molecule junctions.

[Abstract] [DOI] [pdf]
The conductance of a system containing two tunnel point-contacts and a single subsurface scatterer in the presence of a magnetic ¯eld is investigated theoretically. A general formula for the dependence of the conductance on the distance between contacts, the defect position, and the magnetic ¯eld is obtained. It is shown that in the presence of a magnetic ¯eld the conductance undergoes Aharonov-Bohm type oscillations. We ¯nd a simple relation between the period of the oscillations and the depth of the subsurface impurity. On the basis of this fact a new and easy method of determination the depth of the buried impurity is proposed.

[Abstract] [DOI] [pdf]
We present a quantitative analysis of the steady-state electronic transport in a resistive switching device. The device is composed of a thin film of Ag2S (solid electrolyte) contacted by a Pt nano-contact acting as ion-blocking electrode, and a large-area Ag reference electrode. When applying a bias voltage both ionic and electronic transport occurs, and depending on the polarity it causes an accumulation of ions around the nano-contact. At small applied voltages (pre-switching) we observed this as a strongly nonlinear current–voltage curve, which is modeled using the Hebb–Wagner treatment for polarization of a mixed conductor. This model correctly describes the transport of the electrons within the polarized solid electrolyte in the steady-state up until the resistance switching, covering the entire range of non-stoichiometries, and including the supersaturation range just before the deposition of elemental silver. In this way, it is a step towards a quantitative understanding of the processes that lead to resistance switching.

[Abstract] [DOI] [pdf]
In this review we present recent theoretical results concerning investigations of single subsurface defects by means of a scanning tunneling microscope (STM). These investigations are based on the effect of quantum interference between the electron partial waves that are directly transmitted through the contact and the partial waves scattered by the defect. In particular, we have shown the possibility imaging the defect position below a metal surface by means of STM. Different types of subsurface defects have been discussed: point-like magnetic and nonmagnetic defects, magnetic clusters in a nonmagnetic host metal, and nonmagnetic defects in a s-wave superconductor. The effect of Fermi surface anisotropy has been analyzed. Also, results of investigations of the effect of a strong magnetic field to the STM conductance of a tunnel point contact in the presence of a single defect has been presented.

[Abstract] [DOI] [pdf]
In a previous paper Ye. S. Avotina et al., Phys. Rev. B 74, 085411 2006, the effect of Fermi surface anisotropy on the conductance of a tunnel point contact with a single point-like defect situated in its vicinity was investigated theoretically. The oscillatory dependence of the conductance on the distance between the contact and the defect was found for a general Fermi surface geometry. In the present paper the method developed in the cited work is applied to the calculation of the conductance of noble metal contacts. An original algorithm, which enables the computation of the conductance for any parametrically specified Fermi surface, is proposed. On this basis a pattern of the conductance oscillations, which can be observed by the method of scanning tunneling microscopy, is obtained for different orientations of the surface for the noble metals.

[Abstract] [DOI] [pdf]
The electronic absorption spectra (UV- visible-NIR) of a range of molecular metal cluster com- pounds, including new spectra of Pts09(phen*)3602s in solution and Auss(PPhs)l~C16 in the solid state, are dis- cussed and compared with the spectra of colloidal par- ticles of the corresponding metals. We consider frontier orbital separations, the development of 'interband' ab- sorptions, the possible appearance of molecular plasma resonances, and charge-transfer in the solid state.
