A nanowire is a nanostructure, with the diameter of the order of a nanometer. Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important.

Band Structure Lab: First-Time User Guide
15 Jun 2009 | | Contributor(s):: Abhijeet Paul, Benjamin P Haley, Gerhard Klimeck
This document provides useful information about Band Structure Lab. First-time users will find basic ideas about the physics behind the tool such as band formation, the Hamiltonian description, and other aspects. Additionally, we provide explanations of the input settings and the results of the...
Can we define unique effective masses in Si nanowires?
out of 5 stars
06 Jul 2008 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise teaches the users that for small nanostructures the concept of the effective mass becomes vague and in order to properly describe nanostructures one has to take into account the numerically calculated dispersion relation. This is clearly illustrated on the example of Si nanowires...
MuGFET: First-Time User Guide
28 Apr 2008 | | Contributor(s):: SungGeun Kim, Sriraman Damodaran, Benjamin P Haley, Gerhard Klimeck
MuGFET is a simulation tool for nano-scale multi-gate FET structures.This document provides instructions on how to use MuGFET. MuGFET users can use also the PROPHET or the PADRE tool. Either of these provide self-consistent solutions to the Poisson and drift-diffusion equation.At the nanometer...

Notes on Scattering and Mobility in 1D, 2D, and 3D
03 Nov 2009 | | Contributor(s):: Dmitri Nikonov, Md. Sayed Hasan, George Bourianoff
Derivation of the phonon-limited mobility is reviewed for electrons in bulk (3D) orquantum confined (2D and 1D) semiconductor structures. Analytical estimates are madethat show the mobility in quantum confined structures is, in general, lower or no higherthan in non-confined ones.
