Description

Near the edge absorption and lifetime of positrons in CdP2 monocrystals irradiated by 10 and 50 MeV electrons and α-particles with E=35MeV in the range of doses 1017-1018 cm-2 has been studied. The absorption edge destruction is related to the appearance of tails of state density in semiconductor forbidden zone. Multistage character of annealing testifies to the existence of a great number of radiation-induced defects in a crystal having a complex lattice. Destruction of complex defects of vacancy type: at T>350 deg C vacancy emptinesses are healed, corresponds to the main stage of annealing (200-300 deg C)
