A few layers of Cu-based (CuZrAlTi) thin-film metallic glasses (TFMGs) were sputtered on hydrothermally synthesized ZnO nanowires/glass and ZnO nanotubes/glass to fabricate UV photodetectors. The few layers of Cu-based TFMG are ultrathin at ∼0.98 nm and have a noncrystalline metal structure according to X-ray diffraction, Raman, photoluminescence, and high-temperature transmission electron microscopy verification. The photoresponse performance of the coated few-layers Cu-TFMG samples was enhanced 1680-7700% compared with the noncoated sample. The few-layers Cu-TFMG has high transmittance ∼90% in the visible band and creates a large capacitor to absorb UV photocurrent and release dark current.
在水热合成的 ZnO 纳米线/玻璃和 ZnO 纳米管/玻璃上溅射了几层 Cu 基（CuZrAlTi）薄膜金属玻璃（TFMG），以制备紫外光探测器。根据 X 射线衍射、拉曼、光致发光和高温透射电子显微镜验证，Cu 基 TFMG 的几层薄膜非常薄，约为 0.98nm，具有非晶态金属结构。与未镀膜样品相比，镀膜后的几层 Cu-TFMG 样品的光电响应性能提高了 1680-7700%。在可见光波段，几层 Cu-TFMG 的透过率高达 90%，形成大电容，吸收紫外光电流并释放暗电流。
