PN Junction Lab: FirstTime User Guide
13 Jun 2009   Contributor(s):: Saumitra Raj Mehrotra, Benjamin P Haley
This firsttime user guide provides introductory material to PN Junction Lab on nanoHUB. The introduction to PN junctions 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,...

Schred: Exercise 1
06 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
