Tunneling
30 Jul 2011  Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This set of slides describes the quantummechanical process for tunneling and how it is accounted for in modeling semiconductor devices. We explain WKB approximation, transfer matrix approach and the TsuEsaki formula for the calculation of the current.

Computational Nanoscience, Lecture 26: Life Beyond DFT  Computational Methods for Electron Correlations, Excitations, and Tunneling Transport
16 May 2008   Contributor(s):: Jeffrey B. Neaton
In this lecture, we provide a brief introduction to "beyond DFT" methods for studying excited state properties, optical properties, and transport properties. We discuss how the GW approximation to the selfenergy corrects the quasiparticle excitations energies predicted by KohnSham DFT. For...

Finite Height Quantum Well: an Exercise for Band Structure
31 Jan 2008   Contributor(s):: David K. Ferry
Use the Resonant Tunneling Diodes simulation tool on nanoHUB to explore the effects of finite height quantum wells.Looking at a 2 barrier device, 300 K, no bias, other standard variables, and 3 nm thick barriers and a 7 nm quantum well, determine the energies of the two lowest quasibound states.
