Description

Scattering is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more localized non-uniformities in the medium through which they pass. In conventional use, this also includes deviation of reflected radiation from the angle predicted by the law of reflection. Reflections that undergo scattering are often called diffuse reflections and unscattered reflections are called specular(mirror-like) reflections.

  1. ECE 656 Lecture 26: Mobility in 3D, 2D, and 1D

    Online Presentations | 13 Nov 2009 | Contributor(s):: Mark Lundstrom

    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.Outline:Review of ADP Scattering in 3DADP Scattering in 2D: MCAADP Scattering in 2D:...

    Online Presentations | 08 Sep 2008 | Contributor(s):: Mark Lundstrom

    No MOSFET is ever fully ballistic - there is always some carrier scattering. Scattering makes the problem complicated and requires detailed numerical simulations to treat properly. My objective in this lecture is to present a simple, physical picture that describes the essence of the problem and...
