Carbon thin film deposition on plastic using FCVA

Carbon thin film technology has been present in many present applications, the type of substrate it can be deposited on, varies from metal to non-metal. Filtered Cathodic Vacuum Arc (FCVA) is one commonly used technique to deposit carbon thin film. This project will be using FCVA as the main depo...
