Nanoelectronic Modeling Lecture 35: Alloy Disorder in Nanowires

Published on

Abstract

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
