a b s t r a c tThe physical vapor transport (PVT) method is used to grow silicon carbide (SiC) crystals, which are difficult to be grown by other methods. In this paper, a field-coordination theory is involved to optimize the SiC PVT growth process. By using a finite volume-based computational method, we calculate the flow field as well as species concentration field before and after improvement of the thermal design, respectively. The shape of the SiC crystal grown using the improved thermal design is also shown.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
