树形结构Si/ZnO纳米线阵列的制备及光学性能
Synthesis and Optical Properties of Si/ZnO Branched Nanowire Arrays
摘要
Abstract
A low-cost approach for fabricating Si/ZnO branched nanowire arrays was reported. The Si nanowire arrays were prepared on Si ( 100) substrate using a metal-assisted chemical etching process at room temperature. The diameter and distribution are uniform, and the length of Si nanowire could be tuned by varying the etching time. The ZnO film on the surface of Si nanowire was obtained by magnetron sputtering method and then the ZnO nanowires were prepared via hydro-thermal method. The samples were characterized by field-emission scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and photoluminescence (PL). The Si/ZnO branched nanowire arrays are suitable for applications in photovoltaic and photocatalysis.关键词
