Physical Origin of Transient Negative Capacitance in a Ferroelectric Capacitor
Physical Origin of Transient Negative Capacitance in a Ferroelectric Capacitor
The unusual transient negative differential capacitance (NC) of a resistor--ferroelectric (FE) capacitor circuit is of keen interest for use in next-generation transistors, but a clear physical picture and theoretical framework are needed to interpret experiments. The authors show both numerically and analytically that transient NC comes from the mismatch of …
