Abstract :
The influence of accumulation regions of majority carriers in the SIT with high-purity channel on the voltage amplification factor is discussed. The results of a two-dimensional simulation have revealed that a large accumulation region in the high-purity channel, which is related to the Debye length in thickness, restricts extension of the depletion region from the gate, resulting in significant degradation of the voltage amplification factor
