The shapes of synthesized two?dimensional materials

The shapes of as-grown/as-etched two-dimensional (2D) islands are the most recognizable features chemical vapor deposition (CVD) process which reveal a lot information about environment growth/etching, effect substrate and growth/etching kinetics. Here, we summarize experimentally observed CVD-grown 2D materials from previous reports, theoretical understanding on corresponding mechanisms simulations processes. Each part review article is organized by combining fundamental principles that govern crystals during related experimental observations to facilitate readers read understand content. content includes attachment-limited growth, diffusion-limited growth (both with without influence substrate), etching merging considering substrate. We also discuss multilayered CVD—a topic still under development. wish this will guide audience kinetics improve controllable synthesis various materials.
