WebProfessor Eric Pop and Pop Lab at Stanford WebWe analyze high-field transport through a semiconductor body, referred to as a channel, intervening between the source and drain electrodes, similarly to in Part I. A silicon channel with a low doping concentration n0=2.5×10 14 cm-3 …
Web25 de fev. de 2024 · In typical semiconductors with light-hole and heavy-hole bands, the heavy-hole bands become more populated at higher fields because of both the more effective heating of the holes in light-hole bands and the more effective scattering. This causes a mobility reduction. http://poplab.stanford.edu/pdfs/Smithe-HighFieldVsatMoS2-nl18.pdf
WebIt provides a simple and analytical description about hot electron transport, particularly, in semiconductors with higher carrier density where the carrier-carrier collision is much stronger than the single particle scattering.
