Interpretation of an anomalous peak in low-temperature photoluminescence measurements of bulk GaAs[sub 1−x]N[sub x] on GaAs
Published 2013“…Low-temperature 10 K photoluminescence measurements of GaAs1−xNx epitaxial layers grown on GaAs reveal an anomalous second peak in solid-source molecular beam epitaxy. Rapid thermal annealing RTA of a specific GaAsN sample reveals a lower energy peak which redshifts and a higher energy peak which blueshifts under increasing annealing temperature. …”
