Scanning Probe Lithography on InAs Substrate

Houlet L.F., Yamaguchi H., Hirayama Y., NTT Basic Research Laboratories, NTT Corporation, JP

In this study, we focus our interest on patterning a conventional electron beam resist by electron field emission exposure using Atomic Force Microscope (AFM). We have fabricated 50-140 nm deep structures in InAs with the [...]

Modeling and Simulation of Tubular Nanowires

Buldum A., The University of Akron, US

Metallic nanowires have attracted great interest due to their interesting low-dimensional physics and due to possible future technological applications. Most of the previous investigations were related with quantum point contacts and atomic scale nanowires. Recently, [...]

Fabrication of Self Organized Copper Nanostructures on Structureless Surfaces

Kunz R., Kipp L., Skibowski M., Adelung R., Christian-Albrechts-University, DE

An easy way to cover large areas with nano-or microstructures is self-organization. Against intuition, we claim that structureless crystals in terms of surface features are well suitable for self organized structuring on the nano-and micrometer [...]

Size and Strain Rate Effects in Tensil Deformation of Cu Nanowires

Liang W., Zhou M., Georgia Institute of Technology, US

Nanoscale plasticity has drawn significant attention in recent years. Extensive Experimental and numerical studies have been conducted in this field. In previous molecular dynamics (MD) simulations, the Nose-Hoover isothermal procedure was often used to maintain [...]

Three-dimensional, Full-band, Quantum Modeling of Electron and Hole Transport Through Si/SiGe Nano-structures

Rivas C., Lake R., University of California, US

Full-band, three-dimensional (3D), atomistic, non-equilibrium Green fuction simulations are used to model Si nanowires. Full-band and single band calculations are compared. The effect of surface passivation is analyzed in the full-band simulations. Our approach to [...]

Zero Bias Anomalies in Electrochemically Fabricated Atomic-Scale Metal Junctions

Natelson D., Yu L.H., Rice University, US

Metallic nanojunctions (MNJ) are unique tools for examining electronic transport, correlations, quantum coherence, and disorder at the atomic scale. Extensive progress has been made in understanding clean MNJs fabricated in ultrahigh vacuum (UHV) by the [...]

Liang W., Zhou M., Georgia Institute of Technology, US

Nanoscale plasticity has drawn significant attention in recent years. Extensive Experimental and numerical studies have been conducted in this field. In previous molecular dynamics (MD) simulations, the Nose-Hoover isothermal procedure was often used to maintain [...]

Quantum Transport in Nanotube Transistors

Leonard F., Sandia National Laboratories, US

We discuss recent calculations of electronic transport in a 10 nm long, three-terminal carbon nanotube device. By calculating self-consistently the electrostatic potential and charge in the device, we obtain the band bending along the nanotube [...]

Monte Carlo Simulation Study of Mechanical Properties of Au Nanowires

Tanimori S., Shimamura S., Yamaguchi University, JP

We have carried out Monte Carlo simulations of elongation and shear of Au nanowires to investigate their mechanical properties. We have followed stable atomic arrangements in the nanowires during deformation. The Morse potential has been [...]
