Notes on the Ballistic MOSFET
08 Oct 2005  Publications  Contributor(s): Mark Lundstrom
When analyzing semiconductor devices, the traditional approach is to assume that carriers scatter frequently from ionized impurities, phonons, surface roughness, etc. so that the average distance between scattering events (the socalled meanfreepath, λ) is much shorter than the device. When...

Simple Theory of the Ballistic MOSFET
11 Oct 2005  Online Presentations  Contributor(s): Mark Lundstrom
Silicon nanoelectronics has become silicon nanoelectronics, but we still analyze, design, and think about MOSFETs in more or less in the same way that we did 30 years ago. In this talk, I will describe a simple analysis of the ballistic MOSFET. No MOSFET is truly ballistic, but approaching this...

Understanding Phonon Dynamics via 1D Atomic Chains
04 Apr 2006  Online Presentations  Contributor(s): Timothy S Fisher
Phonons are the principal carriers of thermal energy in semiconductors and insulators, and they serve a vital role in dissipating heat produced by scattered electrons in semiconductor devices. Despite the importance of phonons, rigorous understanding and inclusion of phonon dynamics in...
