Abstract
Photoluminescence due to radiation defects in silicon doped with Ge at a co ncentration of 2 x 10(20) cm(-3) and subjected to neutron irradiation and s ubsequent annealing is analyzed and compared to that of silicon crystals co ntaining less or no Ge. Several spectra are ascribed to centers incorporati ng Ge atoms. At concentrations of the order of 10(20) cm(-3) the Ge atoms a re found to be the main sinks for the Frenkel pair components.
