Emerging two‐dimensional (2D) materials have stimulated tremendous scientific and industrial interests due to their diverse and tunable physical, chemical, and mechanical properties. The scalable production of high‐quality wafer‐scale 2D materials has become significantly essential to bring us closer to practical industrial applications, particularly in electronic devices. Vapor‐phase growth provides attractive opportunities for the synthesis of large‐area and high‐quality 2D materials. In this review, we will emphasize vapor‐phase growth strategies from three aspects, including suppressing nucleation, seamless stitching, and evolutionary selection growth. We discuss the general understanding of the related fundamental mechanism and specific parameter optimization from precursors and substrate design to the adjusting of growth parameters (temperature and pressure). Meanwhile, we present other strategies to produce various kinds of wafer‐scale 2D materials. Finally, we conclude the current challenges and future directions in this developing field. This work may inspire researchers to better design routes in the synthesis of wafer‐scale 2D materials with high quality.

Recently, many breakthroughs have been made in graphene research, allowing scientists to explore and understand the material world from a two‐dimensional (2D) perspective. The interface issue of graphene is the most important, because all of its atoms are exposed to the interface for this atomically thin material. The 2D nature necessitates a sensitive and non‐destructive interface probe to detect the structure and properties. Synchrotron radiation (SR) characterization techniques, with the ultra‐high resolution and extremely wide energy range, have been utilized with increasing frequency to explore the challenging interface sciences. In this review, these interface characterization techniques based on SR and how they monitor the structure evolution of graphene in different interfaces such as graphene–substrate and graphene–graphene interface are first introduced. Graphene's layer number, interlayer spacing, and stacking order are governed by these interfaces, determining the final properties. Then, the property detection and modulation in different interfaces of graphene are also discussed. Finally, the current challenges and outlook on the future development for SR techniques to characterize graphene interface are presented.
