▎ 摘  要

We have measured the magneto-capacitance of front-gated capacitor made of Kish graphite to investigate the electronic properties of surface graphene sheets on bulk graphite. The low-field Shubnikov-de Haas oscillations in magneto-capacitance are almost similar with ones of the resistance measurement, which are related to Dirac fermion-like carriers around the H-point such as ones at the K-point in monolayer graphene. At high magnetic fields, the magneto-capacitance oscillations, which may be affected by the surface state on the graphite flake, show slightly different patterns from those in the magneto-resistance.
