Abstract
The properties of GaN layers heavily doped with silicon are investigated via photoluminescence spectroscopy. It is shown that excitons cease localizing on donors at a silicon atom concentration of 1.6 × 1019 cm−3; at higher dopant concentrations, the excitons decay. It is established that the donor binding energy falls as the silicon concentration rises.
