Abstract :
Silicon radiation detectors are employed successfully in high energy physics experiments. In this work emphasis is put on detection, identification and characterization of deep energy levels caused by neutron irradiation. DLTS, C-T as well as C-f measurements were performed on silicon detectors (especially produced for the HI/HERA experiment in Hamburg), which were irradiated by 14.1 MeV neutrons with fluences on the range of 1010-1011 n/cm2. In addition a theoretical model, which describes the frequency and temperature dependencies of the capacitance, is presented
