We report a low temperature photoluminescence study on two identical Al 0.13 Ga 0.87 N/GaN single quantum wells (QWs), which are pseudomorphically grown on either a GaN or an AlGaN buffer layer. The red shift of the QW emission due to the quantum confined Stark effect, is found to be strongest in th
The absorption properties in hetero-polarization GaN/Al x Ga 1Àx N (x ¼ 0:06) quantum well structures are studied in reflection, photoreflection, and photoluminescence excitation spectroscopy and compared with the results of band structure calculations. Above the energy of the main luminescence tran
