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.Outline
