Abstract

Resistivity and photoluminescence measurements have been made on Al-doped CZ Si, with high and with low C concentrations, heat treated at 450°C. The results are compared with those obtained from nominally undoped CZ Si with a low residual B concentration. It is shown that Al acceptors are completely lost, presumably by the removal of Al from substitutional sites by exchange with Si self interstitials generated during oxygen aggregation. Luminescence features observed are tentatively identified with electronic transitions at neutral Al-C and Al-thermal donor complexes.
