Multisubband Monte Carlo Study of Transport, Quantization, and Electron-Gas Degeneration in Ultrathin SOI n-MOSFETs

This paper presents a new self-consistent multisubband Monte Carlo model for electronic transport in the inversion layer of decananometric MOSFETs. The simulator is 2-D in real space and ink⃗-space and accounts for the electron-gas degeneracy in thek⃗-space. Simulation of nanoscale ultra-thin-body silicon-on-insulator MOSFETs shows that the subband structure and the carrier degeneracy strongly affect the transport properties and, in particular, the injection velocity and the channel back-scattering.
