Description
The recent progress in the assembly of 2D van der Waals heterostructures has shown that it is possible to stack virtually every material out of this class enabling a truly unprecedented potential to discover new physical phenomena or to engineer novel electronic functionalities.Despite the vast scope of possibilities enabled by vdW interfaces, a systematic microscopic understanding allowing the interfacial electronic properties to be predicted in terms of those of the constituent monolayers is missing. Here, we develop a strategy based on band-alignment engineering which enables to build vdw interfaces which are either artificial semiconductors or artificial semi-metals.The results of optical and transport measurements demonstrate that the behavior of these interfaces is virtually indistinguishable from that of naturally existing 2D materials.
