Notes on the Ballistic MOSFET
Papers | 08 Oct 2005 | 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 so-called mean-free-path, λ) is much shorter than the device. When...

Field Regulation of Single Molecule Conductivity by a Charged Atom
Online Presentations | 29 Jul 2005 | Contributor(s):: Robert Wolkow
A new concept for a single molecule transistor is demonstrated. A single chargeable atom adjacent to a molecule shifts molecular energy levels into alignment with electrode levels, thereby gating current through the molecule. Seemingly paradoxically, the silicon substrate to which the molecule...
