Semi-insulating LEC gallium arsenide particle detectors were realized with differently manufactured ohmic contacts to improve their performances and possibly avoid injection effects often experienced when the detectors work in full depletion conditions. I-V and C-V measurements on Schottky structures were carried out. Photo-induced current transient spectroscopy and also photo-deep level transient spectroscopy investigations, performed on both planar and Schottky structures, identified electron and hole traps. Detector performances were correlated to defects action.
