Enzheng and Shibin’s paper about 2D perovskite edge states is published in ACS Nano. Congratulations!
We report the formation mechanism and the dynamic nature of edge states on the exfoliated 2D halide perovskites thin crystals. In contrast to other 2D materials, the edge states in 2D perovskites are extrinsic and composed of multiple low energy states due to interaction with moisture. We demonstrate that the charge carriers on the dynamically formed edge states are not only long-lived, but also highly mobile and can be conducted along the edges effectively with high mobilities of 5.4-7.0 cm2V-1s-1. This work provides significant insights on the origin of the edge states in 2D perovskites and provides routes to manipulate their optical and electrical properties through controlling their edges.
