  8. Effective mass in quantum well

    Q&A|Closed | Responses: 0

    Hello,

    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?

    Would really...

  10. 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....

  12. 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...

  15. Quantum Wells, Heterostructures and Superlattices

    23 Jul 2010 | | Contributor(s):: Stephen M. Goodnick, Dragica Vasileska

    this is an overview of the analysis and the application of quantum wells, heterostructures and superlattices.

  16. 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...

  17. 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...

  18. 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.

  19. 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...
