Below band-gap optical absorption and photoluminescence excitation spectroscopy at room temperature in low-defect-density bulk GaN:Fe
Original language description
We present a detailed study of the below band-gap optical absorption at room temperature in bulk semi-insulating GaN:Fe versus the Fe-doping. It was established that the 1.24 eV photoluminescence band at 300?K consists of only vibrational replicas of theFe3+ 4T1(G) 6A1(S) internal transition. We also studied the below band-gap photoluminescence excitation of the 1.24?eV band. The identical exponential rise of the photoluminescence excitation and the optical absorption coefficient identify the Fe3+/2+ charge-transfer as the main contributor to the 300?K optical absorption in the range 400-500?nm. Practical implications of these results for Fe-doping determination are discussed.
