摘要	Metal phosphorous tri-chalcogenides are a category of new ternary 2D layered materials with a wide range of tuneable bandgaps (1.23.5eV). These wide-bandgap semiconductors exhibit great potential applications in solar-blind ultraviolet (SBUV) photodetection. However, these 2D solar-blind photodetectors suffer from low photoresponsivity, slow photoresponse speed, and narrow operation spectral region, thereby limiting their practical applications. Here, an ultra-broadband photodetection based on a FePSe3/MoS2 heterostructure with coverage ranging from solar-blind ultraviolet 265nm to longwave infrared (LWIR) 10.6 m is reported. Notably, the device exhibits excellent weak light detection capability. A high photoresponsivity of 33600AW1 and an external quantum efficiency of 1.57107% are demonstrated. A noise-equivalent power as low as 5.7 1016 WHz1/2 and a specific detectivity up to 1.511013cmHz1/2W1 are realized in the SBUV region. The room temperature LWIR photoresponsivity of 0.12AW1 is realized. This work opens a route to design high-performance SBUV photodetectors and wide spectral photoresponse applications. 2022 Wiley-VCH GmbH.
