NEGF theory of quantum photovoltaic devices
22 Sep 2011   Contributor(s):: Urs Aeberhard
Many highefficiency 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....

Electronic Structure and Transport in 3D  Quantum Dots, Nanowires and UltraThin Body Transistors

Atomistic Modeling and Simulation Tools for Nanoelectronics and their Deployment on nanoHUB.org
16 Dec 2010   Contributor(s):: Gerhard Klimeck
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 splitoff 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 NEMO1D paper (Lake et al., JAP 81, 7845 (1997)) to model quantum transport in a lightemitting diode (LED).ANGEL is the first 1Dheterostructure 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 phononlimited 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 nonconfined 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...

NEMO3D
For now this page is a rather empty place holder for references on nanoHUB to the NEMO3D tool.

Bound States Calculation Description
05 Jul 2008   Contributor(s):: Dragica Vasileska
These lectures describe the calculation of the bound states in an infinite potential well, finite potential well and triangular well approximation. At the end, shooting method, that is used to numerically solve the 1D Schrodinger equation, is briefly described.visit www.eas.asu.edu/~vasileskNSF

From 1 well to 2 wells to 5 wells to periodic potentials: an Exercise
02 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise demonstrates that the interaction between the wells lifts the degeneracy of the quasibound states and if in the limit we have infinite periodic potential it leads to formation of energy bands. Notice that when the interaction is less strong the energy levels are more sharp and the...
