Photoluminescence and Acceptor State of Na in ZnSe

概要
- 論文の詳細を見る
Sodium was incorporated into high-purity ZnSe single crystals by dipping the crystal into molten Se-base Na alloys. The I^<Na>_1 line and two types of donor-acceptor pair (DAP) emissions were observed. An acceptor binding energy of 117 meV was obtained for Na by analyzing the selective photoluminescence spectra on the I^<Na>_1 line and the excitation intensity dependence of the peak energy of DAP emissions. It is confirmed that the P emission observed in DAP emission is due to the recombination between the Na acceptor and Ga donor.
