Abstract

This paper investigates the variation of the vacancy defect concentration and hybrid potential of copper and nickel - based epitaxial graphene with temperature by considering the existence of vacancy defects. Moreover, we discuss the impact of atomic non-harmonic vibration on the metal - based epitaxial graphene. First, the concentration of vacancy defects increases nonlinearly with increasing temperature, and the changing rate of the vacancy defect concentration of the metal-based epitaxial graphene with temperature is smaller than that of graphene; Second, the hybrid potential increases with increasing temperature, but not much; Third, the hybrid potential is independent of temperature without considering the atomic non-harmonic vibration which has an important influence on the vacancy defect concentration and the hybrid potential. The higher the temperature is, the more significant the non-harmonic effects are.
