摘要：
An analytic model is developed to determine the gate-substrate potential profile in a heterojunction field-effect transistor photodetector HFETPD. The potential profiles and the associated depletion widths determined by the model are shown to be in excellent agreement with a device simulator which numerically solves the drift-diffusion equations. The behaviour of the active layer depletion width is also studied as a function of gate bias and doping levels in the delta plane, the active layer and barrier layer.
