Atomistic Modeling and Simulation Tools for Nanoelectronics and their Deployment on nanoHUB.org
Online Presentations | 16 Dec 2010 | Contributor(s):: Gerhard Klimeck
At the nanometer scale the concepts of device and material meet and a new device is a new material and vice versa. While atomistic device representations are novel to device physicists, the semiconductor materials modeling community usually treats infinitely periodic structures. Two electronic...

NanoV: Nanowire-based VLSI Design
Downloads | 08 Sep 2010 | Contributor(s):: muzaffer simsir
In the coming decade, CMOS technology is expected to approach its scaling limitations. Among the proposed nanotechnologies, nanowires have the edge in the size of circuits and logic arrays that have already been fabricated and experimentally evaluated. For this technology, logic-level design...

Threshold voltage in a nanowire MOSFET
Animations | 22 Apr 2010 | Contributor(s):: Saumitra Raj Mehrotra, SungGeun Kim, Gerhard Klimeck
Threshold voltage in a metal oxide semiconductor field-effect transistor (better known as a MOSFET) is usually defined as the gate voltage at which an inversion layer forms at the interface between the insulating layer (oxide) and the substrate (body) of the transistor. A MOSFET is said to be...

Notes on Scattering and Mobility in 1D, 2D, and 3D
Teaching Materials | 06 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.
