Effects of Structural Deformation and Tube Chirality on Electronic Conductance of Carbon Nanotubes

Svizhenko A., Maiti A., Anantram M.P., NASA Ames Research Center, US

A combination of large scale classical force-field (UFF), density functional theory (DFT) and tight-binding Green’s function transport calculations is used to study the electronic properties of carbon nanotubes under the twist, bending and AFM-tip deformation. [...]

Effects of Disorder in Reduced Dimensional and Quantum Electronics

Weaver B.D., Aifer E.H., Naval Research Laboratory, US

We discuss the effect of atomic disorder on electronic systems that operate in either reduced dimension or by quantum-mechanical transport. Systems include high electron mobility transistors, tunnel diodes, superconductors, multiquantum well infrared and ultraviolet detectors, [...]

Molecular Electronics: The Experimentalist’s View

Tsui R., Motorola, US

In the last few years, significant experimental advances have been achieved in the utilization of nanoscale molecular components for electronic applications. A variety of materials, including carbon nanotubes, custom-synthesized organic molecules, metallic nanoparticles, and biological [...]

Nanocrystalline Silicon Superlattices for Nanoelectronic Devices

Tsybeskov L., University of Rochester, US

This paper provides a brief introduction to a novel nanostructured system consisting of ordered layers of Si nanocrystals separated by atomically flat and chemically abrupt layers of amorphous silicon dioxide with thickness of several nanometers. [...]

Molecular Conductors: Paradigms and Possibilities

Ghosh A.W., Paulsson M., Datta S., Purdue University, US

The purpose of this talk is to present simple models (whose parameters are extracted from first-principles theory) that capture the basic physics of molecular conduction and provide intuitive explanations for a number of features in [...]

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 [...]

Molecular Electronics by the Numbers

Pantelides S.T., Di Ventra M., Lang N.D., Rashkeev S.N., Vanderbilt University, US

The paper gives an overview of recent work by the authors in first-principles, parameter-free calculations of electronic transport in molecules in the context of experimental measurements of current-voltage (I-V) characteristics of several molecules by Reed [...]

Field Emission of Carbon Nanotubes and the Electronic Structure of Fullerenes Encapsulated in Carbon Nanotubes

Cho Y., Kim G., Lee S., Ihm J., Seoul National University, KR

We have performed first-principles calculations on the field emission of carbon nanotubes. The three-dimensional character of the current source, as well as the effect of the external electric field, are explicitly considered. The calculated electron-leakage [...]

FE-Simulation of Fast Switching Behavior of Magnetic Nanoelements

Fidler J., Schrefl T., Forster H., Suess D., Dittrich R., Vienna University of Technology, AT

Numerical micromagnetics is an essential tool to optimize magnetic storage media, spin electronic devices, such as MRAM and microsensors. The application of these devices requires a profound knowledge of the reversal mechanism. In nanostructured magnets [...]
