Field Emission of Carbon Nanotubes and the Electronic Structure of Fullerenes Encapsulated in Carbon Nanotubes
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 [...]
Molecular Electronics by the Numbers
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 [...]
Quantum Transport in Nanotube Transistors
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 Conductors: Paradigms and Possibilities
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 [...]
Nanocrystalline Silicon Superlattices for Nanoelectronic Devices
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 Electronics: The Experimentalist’s View
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 [...]
Effects of Disorder in Reduced Dimensional and Quantum Electronics
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, [...]
Effects of Structural Deformation and Tube Chirality on Electronic Conductance of Carbon Nanotubes
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. [...]
Molecular Control of the Drain Current in a Buried Channel MOSFET
We present results from a buried channel MOSFET with a molecular monolayer deposited on the surface. After attachment of the monolayer, the threshold voltage of the device shifts by approximately – 4.5 V. We explain [...]
First-principles Study of Electron Transport through Atomistic Metal-Oxide-Semiconductor Structures
We describe a theoretical scheme to combine first-principles molecular dynamics simulation and non-perturbative scattering theory for transport calculations. We compare our approach with published results for electron transport through a single Al atom. The method [...]
