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.

Nanoelectronic Modeling Lecture 23: NEMO1D - Importance of New Boundary Conditions
09 Mar 2010 | | Contributor(s):: Gerhard Klimeck
One of the key insights gained during the NEMO1D project was the development of new boundary conditions that enabled the modeling of realistically extended Resonant Tunneling Diodes (RTDs). The new boundary conditions are based on the partitioning of the device into emitter and collector...
Nanoelectronic Modeling Lecture 24: NEMO1D - Incoherent Scattering
Incoherent processes due to phonons, interface roughness and disorder had been suspected to be the primary source of the valley current of resonant tunneling diodes (RTDs) at the beginning of the NEMO1D project in 1994. The modeling tool NEMO was created at Texas Instruments to fundamentally...
Nanoelectronic Modeling Lecture 26: NEMO1D -
NEMO1D demonstrated the first industrial strength implementation of NEGF into a simulator that quantitatively simulated resonant tunneling diodes. The development of efficient algorithms that simulate scattering from polar optical phonons, acoustic phonons, alloy disorder, and interface...

ANGEL - A Nonequilibrium Green's Function Solver for LEDs
07 Feb 2010 | | Contributor(s):: sebastian steiger
Introducing ANGEL, a Nonequilibrium Green’s Function code aimed at describing LEDs.ANGEL uses a description close to the classic NEMO-1D paper (Lake et al., JAP 81, 7845 (1997)) to model quantum transport in a light-emitting diode (LED).ANGEL is the first 1D-heterostructure NEGF to include the...

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

Notes on Scattering and Mobility in 1D, 2D, and 3D

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.
