Abstract

Hybrid UV-photodetector (PD) design consisted of various compatible nano-material systems are drawing significant research interests due to their improved device tunability and functionality. A hybrid ZnO–MoS₂/HNP UV-PD design is demonstrated by the mixture layer of zinc oxide (ZnO) quantum dot (QD) and molybdenum di-sulfate (MoS₂) nanoparticles (NPs) on the plasmonic hybrid PdAu NP template. The proposed design exhibits an excellent photocurrent of 1.45×10⁻³ A under the 54.9 mW/mm² at ± 10 V due to a dual step enhancement of photo-carrier injection. It then leads to the significantly improved performance factors of photo-responsivity 1430 mA/mm² and detectivity 4.50 × 10¹⁰ jones at 0.34 mW/mm². The rise time (T_r) and fall time (T_f) of 3.37 and 0.35 s are obtained for the ZnO–MoS₂/HNP PD. The demonstrated performance factors indicate that the hybrid ZnO–MoS₂/HNP UV-PD platform is one of the best UV-PDs as summarized in Table 1.
