MOVPE growth and optical properties of wurtzite InP nanowires with radial InP/InAsP quantum wells

MOVPE growth and optical properties of wurtzite (WZ) InP nanowires (NWs) with radial InAsP/InP quantum wells (QWs) were investigated. InAsP QWs with a pure WZ crystal phase structure were grown using pure WZ-InP NW cores with the crystalline structure controlled by sulphur doping. Single NWs showed photoluminescence attributed to the InAsP QW with WZ crystal phase structure, and peak energy shifts related to the QW width were observed.
