Using above-barrier excitation with a power density of about10 W/cm2 at 13 K, a strong PL emission peak appears on the high-energy side of the three PL peaks originating from theground-state exciton transitions of the three QW’s. This high-energy PL peak with an intensity comparable to the one ofthe other three peaks is located near an excited-subband (n=2) exciton state of the widest QW. By investigating theposition dependence of the PL spectra across a 2-inch wafer, which exhibits a decreasing Al mole fraction x from thecenter to the edge, the PL intensity of the high-energy peak can be correlated with the one of the ground-state in thewidest QW. This correlation indicates that this high-energy PL peak is most likely related to the n=2 exciton state of thewidest QW because of the energy alignment of the excited subband state relative to the barrier band edge.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal
