Abstract: A method of preparing the electronic material called silicon intercalated epitaxial monolayer graphene comprises the steps of growing large scale high-quality graphene on metal surface, depositing silicon on the prepared epitaxial graphene and annealing to high temperature to intercalate the silicon to the interface of graphene and metal surface. Depending on the quantity of the silicon deposited on the graphene surface, the numbers of the silicon layers on the interface can be controlled and adjusted.
