A Pursuit of GeometryCentric Solutions to Engineering Problems
04 Apr 2017   Contributor(s):: Ganesh Subbarayan
The main thesis of this talk is that a geometrycentric viewpoint during analysis of behavior is not only necessary to ensure the accuracy of the predicted shapes of boundaries and interfaces, but also enables efficient solution. Furthermore, I will demonstrate that an explicit parametric...

Computational Nanoscience, Lecture 21: Quantum Monte Carlo, part II
15 May 2008   Contributor(s):: Jeffrey C Grossman, Elif Ertekin
This is our second lecture in a series on Quantum Monte Carlo methods. We describe the Diffusion Monte Carlo approach here, in which the approximation to the solution is not restricted by choice of a functional form for the wavefunction. The DMC approach is explained, and the fixed node...

Diffusion of holes and electrons
10 Apr 2010   Contributor(s):: Saumitra Raj Mehrotra, Gerhard Klimeck
Diffusion is a process of particles distributing themselves from regions of high to low concentrations. In semiclassical electronics these particles are the charge carriers (electrons and holes). The rate at which a carrier can diffuse is called diffusion constant with units of cm2/s. The...

Drift Diffusion Lab: FirstTime User Guide
13 Jun 2009   Contributor(s):: Saumitra Raj Mehrotra, Benjamin P Haley
This firsttime user guide provides introductory material to Drift Diffusion Lab on nanoHUB. It includes a tour of the Rappture interface, which notes key inputs and typical outputs. It also provides an introduction to concepts of drift and diffusion in a semiconductor. We discuss the default...
