Abstract

We report high-performance 0D-2D hybrid photodetectors integrated with tunable band gap perovskite (CsPbI₃, Cs_XFA_X-1PbI₃, and FAPbI₃) quantum dots and MOCVD-grown bilayer MoS₂. In our hybrid structure, the lead halide PQDs can be utilized as an absorbing layer of light of specific wavelengths and transfer the photogenerated carriers to the MoS₂ transport layer. With tunable wavelength lead halide PQDs, the 0D-2D hybrid photodetector shows a high responsivity up to 10⁷ AW^-1 and high specific detectivity exceeding 10¹³ Jones due to the difference in the built-in potential between PQDs and multilayer MoS₂ layers. This work proposes the possibility of fabricating high-performance photodetectors by hybridizing PQDs of various band gaps with 2D materials.
