IMPURITY EFFECTS IN NEUTRON-IRRADIATED SILICON AND GERMANIUM.

Abstract

The influence of dopant impurities and oxygen on the degradation of the electrical properties of silicon by neutrons was investigated. Arsenic, phosphorous gallium and boron were utilized as dopants over a wide range of carrier concentrations in material grown by different techniques. The effects of neutron irradiation on carrier lifetime, mobility, and carrier concentration were measured as a function of temperature and annealing. No dependence of the rate of lifetime degradation on impurity was observed, although some differences were seen in carrier concentration and mobility changes. (Author)
