Optical properties of Al_xGa_(1-x)As/AlAs quantum wires under high density excitation

摘要

Optical properties of semiconductors under high density excitation have been extensively investigated since various phenomena due to many-body effects appear. In particular, low-dimensional quantum structures such as quantum wires have attraced a great interest in their novel physical properties. We pay attention to the many-body effects of electron-hole paris in quantum wire structure under the high density excitation. IN this paper, we have studied photoluminescence (PL) properties in Al_xGa_(1-x)As/AlAs quantum wires (QWRs) under the high density excitation.
