Abstract
The current-voltage (I–V) characteristics of the ferroelectric potassium nitrate (KNO3): poly vinyl fluoride (PVF) has been investigated. The current–voltage characteristics gave the peak-to-valley ratio (PVR) of 4.5:1 for the forward bias voltage of +2V at room temperature. The non-linear and butterfly features of the capacitance-voltage (C–V) curves strongly corroborate the presence of ferroelectricity in the composite films. The Negative Differential Resistance (NDR) phenomenon has been observed with applied dc bias voltages and indicates the Resonant Tunneling type characteristics.
