  3. Nanoelectronic Modeling Lecture 35: Alloy Disorder in Nanowires

    05 Aug 2010 | Online Presentations | Contributor(s): Gerhard Klimeck, Timothy Boykin, Neerav Kharche, Mathieu Luisier, Neophytos Neophytou

    This presentation discusses the consequences of Alloy Disorder in unstrained strained AlGaAs nanowires

    • Relationship between dispersion relationship and transmission in perfectly ordered wires
    • Band folding in Si nanowires
    • Tranmisison in disordered wires – relationship to an approximate bandstructre
    • Reminder of the origin of bandstructure and bandstructure engineering
    • Localization of wavefunctions

    Learning Objectives:

    1. Alloy wires are NOT smooth
    2. “Conduction band edge” flucatuates locally
    3. Dispersion changes
    4. Transmission and Density of states show localization effects
