Abstract :
The performance of radiation detectors which are based on semi-insulating GaAs with the PC blocking electrode prepared by MBE, as well as the Schottky electrode is presented. The role of the detector geometry including base thickness and area of the blocking contact is studied. The influence of the back electrode technology and detector operation temperature is also illustrated.
