Description

A nanotransistor is a transistor whose dimensions are measured in nanometers. Transistors are used for switching and amplifying electronic signals. When combined in the millions and billions, they can be used to create sophisticated programmable information processors.

    05 Jan 2006 | | Contributor(s):: Umberto Ravaioli

    Size quantization is an important effect in modern scaled devices. Due to the cost and limitations of available full quantum approaches, it is appealing to extend semi-classical simulators by adding corrections for size quantization. Monte Carlo particle simulators are good candidates, because a...

  7. Ballistic Nanotransistors - Learning Module

    07 Dec 2005 | | Contributor(s):: Mark Lundstrom

    This resource is an introduction to the theory ballistic nanotransistors. No transistor is fully ballistic, but analyzing nanotransistors by neglecting scattering processes provides new insights into the performance and limits of nanoscale MOSFETs. The materials presented below introduces the...

  8. Notes on the Ballistic MOSFET

    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...
