摘要
A high-performance 2D photodetector based on a bilayer structure comprising a WSe2 monolayer and CH3NH3PbI3 organolead halide perovskite is reported. High performance is realized by modification of the WSe2 monolayer with laser healing and perovskite functionalization. After modification, the output of the device was three orders of magnitude better than the pristine device; the performance is superior to that of most of the 2D photodetectors based on transition-metal-dichalcogenides (TMDs). This result indicates that combinatory TMDs-halide perovskite hybrids can be promising building blocks in optoelectronics.
