Abstract :
Wurtzite (WZ) InP nanowires (NWs) with radial InP/InAsP quantum wells (QWs) having an arsenic composition in the rage of 0.43-0.60 were grown using metalorganic vapor phase epitaxy, and their optical properties were investigated. These InAsP QW layers with a high arsenic content and WZ crystal phase were successfully grown using WZ-InP NWs whose crystalline structure was controlled by sulphur doping. Photoluminescence (PL) of individual NWs with radial InP/InAsP QWs was clearly observed at room temperature. The PL wavelengths were successfully controlled by adjusting the radial QW thickness and arsenic composition of InAsP, and emissions in the 1.3-μm region were demonstrated.
