Drift-Diffusion Modeling and Numerical Implementation Details
01 Jun 2010 | Contributor(s):: Dragica Vasileska
This tutorial describes the constitutive equations for the drift-diffusion model and implementation details such as discretization and numerical solution of the algebraic equations that result from the finite difference discretization of the Poisson and the continuity...
From Semi-Classical to Quantum Transport Modeling: Drift-Diffusion and Hydrodynamic Modeling
10 Aug 2009 | Contributor(s):: Dragica Vasileska
This set of powerpoint slides series provides insight on what are the tools available for modeling devices that behave either classically or quantum-mechanically. An in-depth description is provided to the approaches with emphasis on the advantages and disadvantages of each approach. Conclusions...
How Quantum-Mechanical Space-Quantization is Implemented in Schred, Drift-Diffusion (SILVACO ATLAS) and Particle-Based Device Simulators (Quamc2D)
out of 5 stars
27 Jul 2008 | | Contributor(s):: Dragica Vasileska
This brief presentation outlines how one can implement quantum-mechanical space quantization effects exactly (using Schred) and approximately in drift-diffusion (using SILVACO), as well as particle-based device simulators (using Quamc2D).
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...

Numerical solution of the Drift-Diffusion Equations for a diode
28 May 2010 | | Contributor(s):: Dragica Vasileska
This material describes the implementation and also gives the source code for the numerical solution of the Drift-Diffusion equations for a PN Diode. The code can be easily generalized for any 2D or 3D device.
