Graphene grown on SiC has an interfacial layer, called the buffer layer, between graphene and SiC, which degrades the high temperature mobility of graphene. For understanding the effect of the buffer layer on the carrier mobility of graphene, we investigated the electronic properties of CVD-grown graphene transferred onto the buffer layer. Transferred graphene exhibited very weak electronic interaction from the buffer layer, compared with epitaxially grown graphene on SiC.
