To Further boost its SiC technology, Infineon invested a lot into testing on-state oxide reliability of electrically screened SiC MOSFETs plus the off state oxide stress because of the electric field disorders in SiC power devices. Another means of growing graphene would be thermally decomposing SiC at a high temperature https://www.quora.com/profile/Trevor-Flatcher-2/Thermal-Conductivity-of-Silicon-Carbide-and-Heat-Dissipation-Solutions-for-Electronic-Devices-Thermal-management-is-a-c
