The unique properties of 2D materials are affected by the discontinuities posed by the structure’s edge. Here, using atomic-resolution scanning transmission electron microscopy and ab initio molecular dynamics simulations, the authors image and explain the formation of specific edge structures on Mo1 − x W x Se2 monolayers under different chemical conditions.
