Abstract

With the scaling down and low-power consumption driven by the growing demand in Internet of things and wearable devices, there is an increasing need for miniaturized, self-powered flexible optoelectronics with the ability of omnidirectional photodetection. In this work, the mixed-dimensional heterojunction near-ultraviolet photodetector of CdS nanobelt/PbI2 nanosheet is prepared by chemical vapor deposition and liquid-phase growth methods. Importantly, the as-fabricated self-powered near-ultraviolet photodetector displays a low Idark of 7×10-14 A, high Ilight/Idark ratio of 2.06×103, fast response times of 581 μs/581 μs and exceptional responsivity and detectivity of 3446.04 mA·W-1 and 9.05×109 Jones profiting from the built-in field. In addition, the flexible near-ultraviolet photodetector exhibits impressive omnidirectional photodetection and robust bending endurance. All the results reveal the technological potency of the mixed-dimensional photodetector for next-generation high-performance near-ultraviolet optoelectronics.
