The effect of addition of WS₂ nanosheets on the performance of ZnO nanorods-based photodetector

Abstract Fabrication of the heterostructure ZnO/transition metal dichalcogenides (TMD) has attracted much attention to improve performance ZnO-based photodetectors. In this work, we report effect addition WS 2 nanosheets on ZnO nanorods based were prepared using hydrothermal method, and few layers by liquid-phase exfoliation. Exfoliated solution was deposited surface spin-coating photodetector calculated via current-voltage measurement in dark under laser light sources with a wavelength UV 365, cyan 505, red 625 nm. The results show that current significantly decreased after surface. detector performances sensitivity is increased from 129% 334%, responsivity 0.93 A/W 1.11 A/W, detectivity 2.5 × 10 9 4.4 Jones. However, both samples cannot be used as visible detectors because low photogenerated current.
