The goal in this lecture is to examine one scattering mechanism (ADP scattering) in 3D, 2D, and 1D to see how the scattering rate changes with dimensionality. Then we’ll compare mobilities in 3D, 2D, and 1D.


  • Review of ADP Scattering in 3D
  • ADP Scattering in 2D: MCA
  • ADP Scattering in 2D: FGR
  • ADP Scattering in 1D: FGR
  • Mobility in 1D, 2D, and 3D


This lecture is based on a set of notes prepared by Drs. George Bourianoff and Dmitri Nikonov of Intel Corporation with additional contributions by Dr. Sayed Hasan of Intel.
