Research Progress on Orientation-Controlled Growth of Two-Dimensional Atomic Crystal Materials
Two-dimensional atomic crystal materials hold significant potential for applications in optoelectronic devices due to their atomic-scale thickness and exceptional optical and electrical properties.The large-area single-crystal synthesis of two-dimensional atomic crystal materials is a fundamental prerequisite for their practical appli-cations.In recent years,achieving large-area single-crystal synthesis by controlling the growth orientation of two-dimensional atomic crystal materials has emerged as a pivotal research direction within the two-dimensional atomic crystal materials field.Although numerous review articles have summarized the research progress in the controlled preparation of two-dimensional atomic crystal materials,a systematic summary specifically on orientation-controlled growth of two-dimensional atomic crystal materials is still lacking.This paper briefly intro-duces the basic properties of two-dimensional atomic crystal materials and the challenges associated with their growth and synthesis.Subsequently,it reviews the latest research progress in orientation-controlled growth of two-dimensional atomic crystal materials,encompassing three primary growth methods and principles:substrate lattice-induced epitaxy,substrate step-induced epitaxy,and self-assembly epitaxy on liquid substrate surfaces.We analyzed the structural characteristics of the two-dimensional atomic crystal materials prepared by each growth method and discussed the types of two-dimensional atomic crystal materials adapted to them,along with their advantages and disadvantages.Finally,we reviewed and analyzed the existing problems in the field of two-dimensional atomic crystal materials orientation-controlled growth and prospected its future development direc-tion.This review provides important theoretical guidance for the controlled preparation of wafer-scale two-dimensional atomic crystal materials materials and the application research of optoelectronic devices.
