取向纳米ZnO/Cu 2 O异质结阵列的制备及光电特性

By electrodepositing a coating of p-type Cu 2 O semiconductor on the aligned n-type ZnO nanowire array substrates, which were synthesized with hydrothermal synthesis method, a new type of ZnO/Cu 2 O core-shell nano- heterojunction photosensitive device was fabricated under different experimental conditions. And the morphologies, microstructures, chemical composition, and optical-electrical characteristics of synthesized ZnO/Cu 2 O nano-hetero- junction samples were researched with SEM, XRD, TEM, XPS, PL, and light response characteristics analytic instruments, respectively. Meanwhile, the effects of experimental parameters on the optical-electrical properties of prepared ZnO/Cu 2 O nano-heterojunction samples were analyzed. The choice of appropriate size of deposition voltage and time is the key impact factor to ensure the nano-heterojunction photosensitive devices have moderate core-shell coating layer thickness and better optical response characteristic. And the results are useful to the ZnO and Cu 2 O semiconductor materials in the application of new photosensitive devices research fields.
