WebThe electron velocity is related to the electric field mobility which can be calculated using v n= −μ n Ε(x)= μ n dx (short channel MOS. (no date). Calculating the electron velocity would be beneficial because at high electric field carriers’ failure to the follow the linear model occurs which is due to velocity saturation effect. For short channel effects there are … WebJun 21, 2024 · In addition, saturation velocity increases with decreasing temperature because of the lower optical phonon occupation ratio at low temperature, in agreement with previous studies on BP .
