Quantum and Thermal Effects in Nanoscale Devices
Online Presentations | 18 Sep 2008 | Contributor(s):: Dragica Vasileska
To investigate lattice heating within a Monte Carlo device simulation framework, we simultaneously solve the Boltzmann transport equation for the electrons, the 2D Poisson equation to get the self-consistent fields and the hydrodynamic equations for acoustic and optical phonons. The phonon...

Lecture 6: Quantum Transport in Nanoscale FETs
Online Presentations | 12 Sep 2008 | Contributor(s):: Mark Lundstrom
The previous lessons developed an analytical (or almost analytical) theory of the nanoscale FET, but to properly treat all the details, rigorous computer simulations are necessary. This lecture presents quantum transport simulations that display the internal physics of nanoscale MOSFETs. We use...

Lecture 4A: Energy Exchange and Maxwell's Demon
Online Presentations | 02 Sep 2008 | Contributor(s):: Supriyo Datta
Objective: To incorporate distributed energy exchange processes into the previous models from lectures 1 through 3 which are based on a "Landauer-like picture" where the Joule heating associated with current flow occurs entirely in the two contacts.Although there is experimental evidence that...
