Properties of Zn-Doped P-Type In0.53Ga0.47As on InP Substrate

Abstract
Zn-doping in In0.53Ga0.47As was investigated. The dependence of the resistivity and Hall mobility of Zn-doped In0.53Ga0.47As upon the hole concentration is found to be the same as that of Zn-doped In0.15Ga0.85As. Photoluminescence in Zn-doped In0.53Ga0.47As is investigated in relation to hole concentration. In0.53Ga0.47As homojunction diodes are made, and minoritycarrier diffusion lengths of holes and electrons are derived from the EBIC (electron beaminduced current) intensity which is dependent upon the distance from the junction interface.
