Similarity of the 3.42 eV and near-band-edge 3.47 eV luminescence bands in GaN

T. V. Shubina, S. V. Ivanov, V. N. Jmerik +8

We demonstrate that the 3.42 eV photoluminescence (PL) band in GaN is of the same intrinsic origin as the near-edge $\sim$3.47 eV band, but arises from regions of inversed polarity…
