Visualizing band offsets and edge states in bilayer–monolayer transition metal dichalcogenides lateral heterojunction

Heterojunctions of two-dimensional materials are used to design electronic and optoelectronic devices. Here, the authors show that zigzag terraces between monolayers and bilayers form atomically sharp type-I heterojunctions, resulting in a wire-like interface both in WSe2 and in MoSe2.
