Exciton binding energies and band gaps in GaN bulk crystals
Photoluminescence and two-photon measurements were performed on hexagonal bulk GaN. From photoluminescence we have obtained the energies of free IS excitons, from two-photon spectroscopy the energies of 2P excitons. These results together allow an accurate determination of exciton binding energies a...
