01 Jun 2010  Contributor(s):: Dragica Vasileska
This tutorial describes the constitutive equations for the driftdiffusion 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 SemiClassical to Quantum Transport Modeling: DriftDiffusion 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 quantummechanically. An indepth description is provided to the approaches with emphasis on the advantages and disadvantages of each approach. Conclusions...

Homework Exercise on Bipolar Junction Transistors
30 Mar 2008   Contributor(s):: Saumitra Raj Mehrotra, Muhammad A. Alam, Gerhard Klimeck
The tutorial questions are based on the Bipolar Junction Transistor Lab v1.0 available online at Bipolar Junction Transistor Lab. Students are asked to find the emitter efficiency, the base transport factor, current gains, and the Early voltage. Also a qualitative discussion is requested.NCN@Purdue

MOSFet: FirstTime User Guide
13 Jun 2009   Contributor(s):: Saumitra Raj Mehrotra, Benjamin P Haley
This firsttime user guide provides introductory material to MOSFet on nanoHUB. The introduction to MOSFETs and SOIMOSFETs is followed by a tour of the Rappture interface, which notes key inputs and typical outputs. We discuss the default simulation (what happens if you don't change any inputs,...

Numerical solution of the DriftDiffusion 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 DriftDiffusion equations for a PN Diode. The code can be easily generalized for any 2D or 3D device.
