Mechanical and electrical properties of Ni nanocontacts

2006 IEEE Nanotechnology Materials and Devices Conference, 2006

The dynamic deformation upon stretching of Ni nanowires as those formed in mechanically controllable break junctions is studied. In order to compare with experiments, we also compute the transport properties in the last stages before failure using the first-principles implementation of Landauer's formalism included in our transport package ALACANT.

Geometry dependent I–V characteristics of gold atomic-sized contacts

2009 9th IEEE Conference on Nanotechnology (IEEE-NANO), 2009

Atomic-sized contacts have attracted significant attention by continuing miniaturization of nanoscale electronic components for the two past decades. In present work, the electronic transport properties of gold atomic-sized contacts are studied using the non-equilibrium Green's function technique on the density functional tight binding method for modelling the geometry dependent I-V characteristics. The gold contacts are sandwiched between (001) electrodes, and ...

It is expected that the large spin polarization at the center of nanocontact can be obtained in the large contact length. The small contact length can easily switch from parallel state to anti-parallel ...

The small contact length can easily switch from parallel state to anti-parallel state in spin configuration of two ferromagnetic electrodes.

  • Spin filter behaviour of atomic NiO chains in Ni nanocontacts

    Contrary to the antiferromagnetic and insulating character of bulk NiO, we show by means of ab initio quantum transport calculations that short atomic NiO chains suspended between Ni nanocontacts can become strongly spin- polarized conductors. They could thus serve as nanoscopic spin filters. Here we study the stability of our results against geometrical distortions of the atomic chain and the nanocontact.

  • AFM technicques for nanostructured materials used in optoelectronic and gas sensors

    Structural and electrical properties of nanostructured materials for optoelectronic and gas sensors have been studied by atomic force microscopy (AFM). The original technique, based on combined conductive AFM, allows analyzing of electrical properties with high lateral resolution. This technique was applied for conductance and homogeneity study of In nanoislands formed on monocrystalline PbTe on Si. Original C-AFM methodic allows performing of localization and evolution of specific conductive areas in In/PbTe nanocontacts. For gas sensitive materials based on tin dioxide the evolution of fractal aggregates can be controlled by thermodynamic and kinetic conditions of sol-gel synthesis. Fundamental evolution steps of fractal systems based on tin dioxide were demonstrated by atomic force microscopy: diffusion-limit aggregation, cluster-cluster aggregation, formation of percolating network and 3D-net nanostructures.

  • The Dependence of Vortex Oscillation Frequency on Small In-Plane Magnetic Fields in Spin-Valve Nanocontacts

    In this work we investigate the magnetic field dependence of the precession frequency of vortex states in spin-valve nanocontacts with an amorphous CoFeB free layer and an artificial antiferromagnet as polarizer. The nanocontacts have radii between 70 and 90 nm. We show that the excitation frequency in these devices responds to small, in-plane magnetic fields along the easy and hard axis directions. The characteristics of the frequency response depend on the generated magnetic configuration under the nanocontact. This, in turn, results from the combined effect of the applied magnetic field and the current-generated Oersted field. Taking also into account the relative large nanocontact radii, a variety of vortex excitation modes can arise with distinctive frequency versus field responses, some of which could be considered for magnetic field sensing applications.

  • Frequency Modulation of a Nano-Oxide Layer-Based Spin-Torque Oscillator With FeCo Nanocontacts

    We studied the effect of injecting a low-frequency (0.5-1 GHz) ac signal on the natural oscillations of a nano-oxide layer-based nanocontact magnetoresistive spin-torque oscillator with multiple Fe50Co50 nanocontacts. We observed a frequency modulation effect with odd-numbered side bands having low amplitudes. Also, no frequency shift at main spectral peak's frequency, typical with nonlinear frequency modulation, was observed. We could not completely explain this behavior, but we propose that this could be related to the internal dynamics of constricted domain walls.

  • Mechanical, Electrical, and Magnetic Properties of Ni Nanocontacts

    The dynamic deformation upon stretching of Ni nanowires as those formed with mechanically controllable break junctions or with a scanning tunneling microscope is studied both experimentally and theoretically. Molecular dynamics simulations of the breaking process are performed. In addition, and in order to compare with experiments, we also compute the transport properties in the last stages before failure using the first-principles implementation of Landauer's formalism included in our transport package ALACANT.
