Abstract

<p>Transition metal dichalcogenides (TMDs), atomically thin layered materials, were attracted intense attention due to its outstanding optical and electrical features. In spite of recent progress in production stage, it is still needed to be improved the quality of TMD crystal. Elucidation of detailed growth mechanism should be important to solve this critical issue in TMD crystal growth. Based on this background, we developed in-situ monitoring CVD, which can directly observe the detailed crystal nucleation and growth dynamics of monolayer and single crystal TMD. Here, we show the recent findings about growth mechanism of TMDs revealed by our study such as diffusion length of precursors, non-classical nucleation, and liquid-solid transfer growth together with their theoretical background.</p>
