Integration of heterogenous materials produces compelling physical phenomena and increased performance of optoelectronic devices. In this work, we integrate CsPbBr3 microplate with WS2 monolayer to investigate the interfacial carrier transfer mechanism in the heterojunction. The quenching of photoluminescence (PL) emission from CsPbBr3 and WS2 after heterostructure formation indicates efficient charge transfer in the junction. Low-temperature PL spectra reveal that the decreasing PL of WS2 arises from the vanishing of biexcitons. Photodetection based on the WS2/CsPbBr3 heterostructure is demonstrated. The higher performance from the junction further certifies the occurrence of charge transfer in the heterojunction.
