Effective mass in quantum well
Closed | Responses: 0
I would like to know if in a square quantum well, if effective mass of electron in well is always less than effective mass in barrier? if yes, then why is that?

NEGF theory of quantum photovoltaic devices
22 Sep 2011 | | 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 dimensional absorbers such as quantum wells, wires and dots in the implementation of these concepts....

At the nanometer scale the concepts of device and material meet and a new device is a new material and vice versa. While atomistic device representations are novel to device physicists, the semiconductor materials modeling community usually treats infinitely periodic structures. Two electronic...

Nanoelectronic Modeling Lecture 25b: NEMO1D - Hole Bandstructure in Quantum Wells and Hole Transport in RTDs
09 Mar 2010 | | Contributor(s):: Gerhard Klimeck
Heterostructures such as resonant tunneling diodes, quantum well photodetectors and lasers, and cascade lasers break the symmetry of the crystalline lattice. Such break in lattice symmetry causes a strong interaction of heavy-, light- and split-off hole bands. The bandstructure of holes and the...
ANGEL - A Nonequilibrium Green's Function Solver for LEDs
07 Feb 2010 | | Contributor(s):: sebastian steiger
Introducing ANGEL, a Nonequilibrium Green’s Function code aimed at describing LEDs.ANGEL uses a description close to the classic NEMO-1D paper (Lake et al., JAP 81, 7845 (1997)) to model quantum transport in a light-emitting diode (LED).ANGEL is the first 1D-heterostructure NEGF to include the...
Notes on Scattering and Mobility in 1D, 2D, and 3D
06 Nov 2009 | | Contributor(s):: Dmitri Nikonov, Md. Sayed Hasan, George Bourianoff
Derivation of the phonon-limited mobility is reviewed for electrons in bulk (3D) orquantum confined (2D and 1D) semiconductor structures. Analytical estimates are madethat show the mobility in quantum confined structures is, in general, lower or no higherthan in non-confined ones.
Comparison of PCPBT Lab and Periodic Potential Lab
10 Aug 2009 | | 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 completely two different sets of tools and validate the obtained results. In this presentation we provide...
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...
