Paper Abstract

An analytical mathematical model of the heterojunction photodiode is presented. The modified formula for the thermionic emission current at the abrupt heterojunction is used. Steady state photodiode parameters and the current frequency response to a small optical modulating signal are calculated. Derived general formulae are applied to the N- AlGaAs/p+-GaAs heterojunction.
