摘要
Cubic GaN films on GaAs (001) substrates which show a low-temperature photoluminescence (PL) without the deep-level orange (2.0 to 2.1 eV) band were grown by metalorganic vapor phase epitaxy (MOVPE). The orange luminescence recovers its relative intensity at room temperature, though the dominance of band-edge free exciton is still significant. The surface morphology was much smoother and the inclusion of hexagonal phase was much reduced for the samples with the suppressed orange band. It is suggested that the role of the GaN buffer layer is very essential in the optimized growth for high optical quality films, providing a flat cubic structure template as well as avoiding thermal damage of GaAs surface at high temperatures.
