Remote epitaxy has opened novel opportunities for advanced manufacturing and heterogeneous integration of two-dimensional (2D) materials and conventional (3D) materials. The lattice transparency as the fundamental principle of remote epitaxy has been studied and challenged by recent observations defying the concept. Understanding remote epitaxy requires an integrated approach of theoretical modeling and experimental validation at multi-scales because the phenomenon includes remote interactions of atoms across an atomically thin material and a few van der Waals gaps. The roles of atomically thin 2D material for the nucleation and growth of a 3D material have not been integrated into a framework of remote epitaxy research. Here, we summarize studies of remote epitaxy mechanisms with a comparison to other epitaxy techniques. In the end, we suggest the crucial topics of remote epitaxy research for basic science and applications.
远程外延为二维（2D）材料和传统（3D）材料的先进制造及异质集成开辟了新机遇。作为远程外延基本原理的晶格透明度，已受到近期违背该概念的观测结果的研究和挑战。理解远程外延需要一种多尺度的理论建模与实验验证相结合的方法，因为该现象包括跨越原子级薄材料和几个范德华间隙的原子远程相互作用。原子级薄的二维材料在三维材料成核与生长中的作用尚未被纳入远程外延研究框架。在此，我们通过与其他外延技术的比较，总结了远程外延机制的研究。最后，我们提出了远程外延在基础科学和应用研究中的关键课题。
