The physical nature of energy transport by two carriersâ€”electrons and phonons--will be explored from basic principles using a common Landauer framework. Issues including the...]]> 1 Wed, 23 Mar 2011 19:36:00 -0400 Boltzmann Transport Equation and Scattering Theory http://nanohub.org/resources/10575http://nanohub.org/resources/10575 In this presentation we give simple derivation of the Boltzmann transport equation, describe the derivation of Fermi's Golden Rule, and present the derivation of most common scattering mechanisms in semiconductors.]]> 39 Tue, 01 Feb 2011 05:11:01 -0500 2010 Nano-Biophotonics Summer School @ UIUC Lecture 18 - Propagation, scattering and inverse scattering of evanescent fields http://nanohub.org/resources/10373http://nanohub.org/resources/10373 1 Thu, 13 Jan 2011 21:41:08 -0500 2010 Nano-Biophotonics Summer School @ UIUC Lecture 23 - Scattering, Absorbing, and Modulating Nanoprobes for Targeted Imaging and Therapy http://nanohub.org/resources/10378http://nanohub.org/resources/10378 1 Thu, 13 Jan 2011 21:41:08 -0500 Inelastic Scattering in NEGF: Matlab Implementation and Exercises http://nanohub.org/resources/10262http://nanohub.org/resources/10262 A set of Matlab scripts has been developed illustrating the treatment of inelastic scattering in non-equilibrium Greens function (NEGF) based quantum transport models.
