A van der Waals (vdW) heterostructure is formed by combining multiple materials through vdW bonds. It can combine the advantages of electronic, optical, thermal, and magnetic properties different 2D has potential to develop into next generation high-performance functional devices. Herein, current research advances heterostructures are reviewed. First, fabrication methods physical structures summarized. The 2D/nD (n = 0,1,2,3) mixed-dimensional discussed in detail. Second, a new type introduced based on two-dimensional electron gas with nanoscale junction interface. Finally, application prospects photoelectric memory devices further outlined combing applications neural networks. This review shows that have great high integration, energy harvesting, logical operations, it provides directions suggestions for future environmentally friendly, high-performance, smart
