▎ 摘  要

The discovery of the 'magic angle' in twisted bilayer graphene (tBLG) triggered tremendous interests in the studies of twist-stacked 2D materials and symbolized the onset of 'twistronics'. The unprecedented properties exhibited by twist-stacked 2D materials are enabled by simply stacking 2D materials with a twist angle. However, it is by no means trivial to establish such material systems in high quality and efficiency. The assembly technologies enabling the construction of twist-stacked 2D materials are critical to achieve the desired properties. Here, we review the state-of-the-art mainstream assembly technologies to produce twist-stacked 2D materials, by using tBLG as a representative materaisl system. We analyzed the advantages and disadvantages of bottom-up and top-down assembly techniques, discussed the assemblies of twist-stacked 2D materials beyond graphene, and proposed potential areas for future investigations to advance the technology to the next level.
