Zero Dimensional-Two Dimensional Hybrid Photodetectors Using Multilayer MoS 2 and Lead Halide Perovskite Quantum Dots with a Tunable Bandgap

We report high-performance 0D-2D hybrid photodetectors integrated with tunable band gap perovskite (CsPbI , Cs FA PbI , and FAPbI ) quantum dots and MOCVD-grown bilayer MoS . 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 MoS transport layer. With tunable wavelength lead halide PQDs, the 0D-2D hybrid photodetector shows a high responsivity up to 10 AW and high specific detectivity exceeding 10 Jones due to the difference in the built-in potential between PQDs and multilayer MoS layers. This work proposes the possibility of fabricating high-performance photodetectors by hybridizing PQDs of various band gaps with 2D materials.
