This study reports ultraviolet (UV) photodetectors based on CuGaO2 (CGO) nanoplates (NPs) and Zn‐doped CGO (CZGO) NP/ZnO nanowire (NW) heterojunctions. The vertical arrays of ZnO NWs are uniformly grown on the surface of hexagonal CZGO NPs and form a high‐density p–n junction. The heterojunctions have better optoelectronic performance parameters than pure CGO NPs. Especially, the responsivity value...
This study reports the synthesis of Zn‐doped hexagonal CuGaO2 (CGO) nanoplates (NPs) and CuGa1−xZnxO2 NPs/ZnO nanowires (NWs) array heterostructures through a hydrothermal method. Remarkably, the absorption properties of CuGa1−xZnxO2 NPs show three absorption regions which can be ascribed to the direct bandgap absorption, defect level absorption, and localized surface plasmon resonance (LSPR) absorption...
