A Monte Carlo particle simulation of a 0.25 μm-long gate (and 0.25 μm-long channel) GaAs MESFET having a practical doping density and sitting on a substrate is carried out. Extremely high values of gm and Idss of 643 mS/mm and 5.35 mA/20 μm were obtained. The near-ballistic nature of the electron transport in the FET was confirmed.
