(Summary description)Precisely designing high-performance semiconductor thin films with vertical structures at the atomic scale can be used in the study of modern integrated circuits and novel materials. One way to obtain such films is to achieve continuous layer-by-layer self-assembly, using two-dimensional building materials stacked vertically and connected by van der Waals forces. Graphene and transition metal dichalcogenides, two-dimensional materials with a thickness of only 1 and 3 atoms, have been used to realize some heterojunctions that were difficult to prepare earlier, and showed relatively excellent physical properties. However, there is no large-scale self-assembly method that can both maintain the intrinsic properties of 2D materials and generate interlayer interfaces, which limits the transformation of layer-by-layer self-assembly methods to a small-scale large-scale fabrication.
