利用时间分辨光致发光光谱研究了p型GaN 2.8 eV发射带的衰减动力学。发光强度呈非指数衰减。衰变动力学与供体-受体对重组一致，对距离随机分布。使用Thomas-Hopfield模型的计算表明，重组涉及深层供体和浅层受体。
The decay dynamics of the 2.8 eV emission band in p-type GaN was investigated using time-resolved photoluminescence spectroscopy. The luminescence intensity decays non-exponentially. The decay dynamics were consistent with donor-acceptor pair recombination for a random distribution of pair distances. Calculations using the Thomas-Hopfield model indicated that recombination involves deep donors and shallow acceptors.
