| Abstract(in English) | Multi quantum wells (MQWs) of AlGaAs/AlAs were grown on (100) GaAs substrates and 23.8° off (100) GaAs substrates towards (111) by molecular beam epitaxy. In the system, X-point electrons are confined in AlAs layers and Γ-point holes are confined AlGaAs layers. The MQWs on 23.8° off substrates have flat interfaces and show strong photoluminescence. The dependence of photoluminescence peak wavelength on Al content of AlGaAs layers indicates that the photoluminescence are attributed to the recombination of X-point electrons are confined in AlAs layers and Γ-point holes are confined AlGaAs layer. Quantum size effects owing to reduction of AlAs layer thickness are given and compared to the result obtained by the quantum energy level and wave function calculation. |
