    Abstract:

    The capacitance-voltage (C-V) curves of Au/P(VDF-TrFE)/Al capacitor were investigated from 200 K to 310 K. An asymmetry of capacitance value at 0 bias voltage under two polarization orientations was observed at room temperature region, which can be applied in the field of non-volatile memory. The capacitance asymmetry decays with reduced temperature and disappears as the temperature is below 230 K. The phenomena is attributed to a pinned dipole layer between P(VDF-TrFE) films and Al metal electrode.
