The Effect of Deposition of MoSe₂ Nanosheets on the Performance of a ZnO-based UV Detector

Abstract ZnO is a promising candidate for ultraviolet (UV) detectors due to its wide bandgap, good transparency, non-toxicity, low cost, and simple preparation. However, the performance of because high recombination rate. One alternative solution fabricating heterostructure with transition metal dichalcogenide (TMD) compound. This study proposes facile fabrication nanorods decorated MoSe 2 nanosheets. nanosheets were synthesized using liquid-phase exfoliation method added surface via spin coating. The photodetector was enhanced addition could trap electrons defect sites ZnO; hence, it decreased dark current slightly increased photocurrent. responsivity from 1.03 1.25 A/W, detectivity 0.82 x 10 9 1.9 Jones, sensitivity 1261% 5701%.
