Charge (Q) vs. voltage (V) characteristic of ferroelectric capacitor. The capacitance is defined as the variation of charge over the variation of applied voltage. The red-colored marks represent the coercive voltages of ferroelectric layer. As the externally applied bias becomes higher than the coercive voltages for forward/reverse voltage sweep, the polarization switching occurs. This renders sudden charge reduction in ferroelectric capacitor. This is illustrated as the “S-shaped” curve in the Q vs. V plot
