Abstract

Abstract: The present study investigates heat transfer on the multi-layered structure with graphene overcoat induced by laser heating. The thermal performance of graphene overcoat is compared with that of diamond like carbon (DLC) overcoat. The temperature rise is lower in the structure with graphene overcoat, which is due to the lower laser energy absorption rate and the higher in-plane thermal conductivity of graphene. The presences of interfacial thermal resistance and surface convection may have more significant effects on the structure with graphene overcoat.
