A study of electrical transport and detection performances of the bulk semi-insulating InP-based detectors of charged particles and γ rays is presented. The best detectors give a charge collection efficiency over 90% and energy resolution about 3% (FWHM) for 5.48 MeV α-particles and an energy resolution about 7% (FWHM) for 122 keV γ-rays at 220 K. Detection performances versus temperature, contact systems and bias voltage polarity have been discussed
