Abstract
The 1.3 eV iron related emission bands in GaN and AlN were analysed by photoluminescence and photoluminescence excitation spectroscopy. The (-/0) acceptor levels of iron in GaN and AlN were determined. A value of 0.5 eV for the GaN/AlN valence band discontinuity is deduced. Values for the GaAs/GaN and the GaAs/AlN valence band discontinuities are discussed.
