Negative capacitance is expected to have applications such as improving performances of capacitor and transistor. In this study, the carbon nanotube film on Zr substrate was used, and a movable Cu electrode was placed near the surface of the CNT/Zr sample in order to measure both capacitance and resistance in various distances between the Cu electrode and CNT/Zr sample. Our results suggest that the tunneling current passing through the structure contributes to the negative capacitance generation.
