Investigation of performance of semi-insulating GaAs detectors for alpha particle detector

In this research work, alpha particle detector is made using semi-insulating GaAs. A surface barrier detector with a semi-insulating GaAs substrate at room temperature with pressure of 10"4 Torr under □-particle radiation with 5.48 Mev of Am241 source, have been under investigation. Energy resolution of 2 and 3 mm schottky diameter have been matured and compared with the effect of voltage variation.
