WebbSaturation velocity is the maximum velocity a charge carrier in a semiconductor, generally an electron, attains in the presence of very high electric fields. When this happens, the semiconductor is said to be in a state of velocity saturation. Charge carriers normally move at an average drift speed proportional to the electric field strength they … WebbThis shows the [8] ATLAS Silvaco International, San Jose, CA, 2000. [9] S. Bandy, C.
