Lecture 3: Resistance-Ballistic to Diffusive
28 Jul 2011 | | Contributor(s):: Mark Lundstrom
The resistance of a ballistic conductor and concepts, such as the quantumcontact resistance, are introduced and discussed. The results are then generalized to treat transport all the way from the ballistic to diffusive regimes.

Diffusion of holes and electrons
15 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 semi-classical 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...
