摘要
Cadmium telluride crystals grown by the Travelling Heater Method (THM) technique have been implanted with hydrogen using protons from 2 kev to 3 Mev. Electrical measurements indicate drastic changes in the concentration of defects, especially in the 0. 15-0. 20 and 0. 45-0. 60 ev bands. However, the modification induced by hydrogen depends on the starting material, implantation and annealing conditions. Resistivity and carrier lifetime are also strongly affected by this treatment.
