Abstract

A high resolution spatially resolved photocurrent system to study bulk non homogeneities in semiinsulating GaAs and InP is described. [Fe+3] distribution is studied in InP. In undoped LEC semiinsulating GaAs a study of the relation of Photoquenching (PQ) and Enhanced Photocurrent (EPC) to the dislocation atmosphere is done.
