The emerging Ruddlesden-Popper two-dimensional perovskite (2D PVK) has recently joined the family of 2D semiconductors as a potential competitor for building van der Waals (vdW) heterostructures in future optoelectronics. However, to date, most reported based on PVKs suffer from poor spectral response that is caused by intrinsic wide bandgap constituting materials. Herein, direct heterointerface (∼0.4 eV) between PVK and ReS2 demonstrated. strong interlayer coupling reduces energy interval at heterojunction region so heterostructure shows high sensitivity with expanding 2000 nm. large type-II band offsets exceeding 1.1 eV ensure fast photogenerated carriers separation heterointerface. When this used self-driven photodetector, it exhibits record detectivity up 1.8 × 1014 Jones, surpassing any devices, an impressive external quantum efficiency 68%.
