Impact of GaN buffer growth conditions on photoluminescence and X-ray diffraction characteristics of MOVPE grown bulk GaN
Properties of metalorganic vapor phase epitaxy (MOVPE) grown GaN bulk layers with varying GaN buffer growth conditions are characterized by low-temperature (6K) photoluminescence (LT-PL) and X-ray diffraction (XRD). [...]
