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

Notes on Scattering and Mobility in 1D, 2D, and 3D
06 Nov 2009 | | Contributor(s):: Dmitri Nikonov, Md. Sayed Hasan, George Bourianoff
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.

Lecture 4: Scattering in Nanoscale MOSFETs
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...

Application of the Keldysh Formalism to Quantum Device Modeling and Analysis
14 Jan 2008 | | Contributor(s):: Roger Lake
The effect of inelastic scattering on quantum electron transport through layered semi-conductor structures is studied numerically using the approach based on the non-equilibrium Green's function formalism of Keldysh, Kadanoff, and Baym. The Markov assumption is not made, and the energy coordinate...
