Abstract
We present a preliminary study of the performance of semi-insulating indium phosphide (InP) crystals and its possible use in nuclear radiation detection at room temperature. Devices having an active area of 12 mm 2 showed a 5% resolution (FWHM) for 5.48 MeV alpha particles. Analyses of photo spectra indicated that the trapping of holes was primarily responsible for degrading the alpha response.
