Teaching Materials (1-5 of 5)

  1. 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.

  2. 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.

  3. 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

  4. 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

  5. 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...
