In this work, we employed a joint use of transmission electron microscopy and CVD, in which the 2D MoSe₂ were directly grown on a graphene membrane based on grids, that enables the microstructural characterization of as-grown MoSe₂ flakes. We further explore the role of hydrogen gas and find: in an argon ambient, the primary products are few-layer MoSe₂ flakes, along with MoO _x nanoparticles; while with the introduction of H₂, single-layer MoSe₂ became the dominant product during the CVD growth. Quantitative analysis of the effects of H₂ flow rate on the flake sizes, and areal coverage was also given. Nevertheless, we further illuminated the evolution of shape morphology and edge structures of single-layer MoSe₂, and proposed the associated growth routes during a typical CVD process.
