Optimization of Transistor Design for Carbon Nanotubes
20 Jan 2006 | | Contributor(s):: Jing Guo
We have developed a self-consistent atomistic simulator for CNTFETs.Using the simulator, we show that a recently reported high-performanceCNTFET delivers a near ballistic on-current. The off-state, however, issignificantly degraded because the CNTFET operates like anon-conventional Schottky...

Quantum Corrections for Monte Carlo Simulation
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...

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...
