Influence of mixed convection in atmospheric pressure chemical vapor deposition of graphene growth

Chemical vapor deposition (CVD) is a well-known process as the most favourable for high-quality large area graphene production. However, it is a complex method where each parameter will contribute to significant effect on the deposition process. One of them, fluid dynamics, was reported to be one of...

Influence of mixed convection in atmospheric pressure chemical vapor deposition of graphene growth
description Chemical vapor deposition (CVD) is a well-known process as the most favourable for high-quality large area graphene production. However, it is a complex method where each parameter will contribute to significant effect on the deposition process. One of them, fluid dynamics, was reported to be one of the major governing factors for better deposition. Heat transfer process at high temperature will influence gas phase dynamics during the deposition process. In this study, the influence of mixed convection in atmospheric pressure CVD (APCVD) on the graphene quality has been systematically investigated. Reynolds number was calculated to identify the gas flow regime as well as to see its effects on the graphene quality. Then, the type of dominant convection inside the reactor was determined using Richardson number (Grashof number/Reynolds number squared).
