Ct. Foxon et al., Improvement of the photoluminescence from gallium nitride layers grown by MBE with an additional incident indium flux, SEMIC SCI T, 13(12), 1998, pp. 1469-1471
The effect of using an indium flux during the MBE growth of GaN layers was
investigated. The properties of these layers were studied using electron pr
obe microanalysis, secondary ion mass spectroscopy, photoluminescence and c
athodoluminescence. The optical properties of the GaN layers are shown to i
mprove as compared with undoped GaN layers grown under nominally the same c
onditions but without an additional indium flux.
