Heterostructured photoconductors based on hybrid perovskites and 2D transition-metal dichalcogenides are fabricated and characterized. Due to the superior properties of CH3 NH3 PbI3 and WS2 , as well as the efficient interfacial charge transfer, such photoconductors show high performance with on/off ratio of ≈10(5) and responsivity of ≈17 A W(-1) . Furthermore, the response times of the heterostructured photoconductors are four orders of magnitude faster compared to the counterpart of a perovskite single layer.
基于杂化钙钛矿和二维过渡金属二卤化物的异质结构光导体被制备和表征。由于 CH3 NH3 PbI3 和 WS2 的优异性质以及有效的界面电荷转移，这种光导体具有高的性能，开关比约为 10(5)，响应度约为 17 A W(-1)。此外，与钙钛矿单层相比，异质结构光导体的响应时间快了四个数量级。
