Abstract
Luminescence in irradiated silicon has been used to determine the thermal stability of the defects responsible for the recombination. It was found that the defect responsible for the zero-phonon line at 0.97 eV has an annealing behavior similar to that of the divacancy and the zero-phonon line at 0.79 eV anneals in a manner similar to the G-15 or K-center. Annealing at temperatures up to 500 °C generates other defects whose luminescence is distinct from that seen previously. Addition of lithium to the material produces defects with new characteristic luminescence. Of particular importance is a defect with a level at Ev − 1.045 eV.Keywords
