Effect of methane concentration on the growth kinetics, microstructure, and crystalline quality of thick MPCVD-grown polycrystalline diamond

In diamond growth using microwave plasma chemical vapor deposition (MPCVD) process, the methane fraction controls the balance between carbon supply and hydrogen etching, while substrate temperature governs surface diffusion and facet‑dependent growth. Yet for polycrystalline diam...
