  3. ANGEL - A Nonequilibrium Green's Function Solver for LEDs

    06 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...

  4. 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...

  5. Band Structure Lab Demonstration: Bulk Strain

    03 Jun 2009 | | Contributor(s):: Gerhard Klimeck

    This video shows an electronic structure calculation of bulk Si using Band Structure Lab. Several powerful features of this tool are demonstrated.

  6. 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

  7. Comparison of PCPBT Lab and Periodic Potential Lab

    04 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...

  9. Energy Bands as a Function of the Geometry of the n-Well Potential: an Exercise

    05 Jul 2008 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

    Explores the position and the width of the bands as a function of the 10-barrier potential parameters.NSF

  10. 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 quasi-bound 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...

  12. Nanoelectronic Modeling Lecture 25b: NEMO1D - Hole Bandstructure in Quantum Wells and Hole Transport in RTDs

    02 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...

  13. NEGF theory of quantum photovoltaic devices

    21 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....
