Recap from Monday
Infinite & Finite Quantum Wells
NEGF theory of quantum photovoltaic devices
22 Sep 2011 | Presentation Materials | Contributor(s): Urs Aeberhard
Many high-efficiency photovoltaics concepts require an advanced control and manipulation of the optoelectronic properties of the active device structure, leading to a prominent role of low...
Tutorial 4b: Introduction to the NEMO3D Tool - Electronic Structure and Transport in 3D
29 Mar 2011 | Online Presentations | Contributor(s): Gerhard Klimeck

Notes on Scattering and Mobility in 1D, 2D, and 3D
06 Nov 2009 | Teaching Materials | Contributor(s): Dmitri Nikonov, Md. Sayed Hasan, George Bourianoff
Derivation of the phonon-limited mobility is reviewed for electrons in bulk (3D) or
quantum confined (2D and 1D) semiconductor structures. Analytical estimates are made
that show the mobility in...
Comparison of PCPBT Lab and Periodic Potential Lab
10 Aug 2009 | Online Presentations | Contributor(s): Abhijeet Paul, Samarth Agarwal, Gerhard Klimeck, Junzhe Geng
This small presentation provides information about the comparison performed for quantum wells made of GaAs and InAs in two different tools. This has been done to benchmark the results from...
For now this page is a rather empty place holder for references on nanoHUB to the NEMO3D tool.
There is a more complete NEMO3D web page that is maintained by the Nanoelectronic Modeling Group of...
