Transient negative differential capacitance (NC), the dynamic reversal of transient capacitance in an electrical circuit is of highly technological and scientific interest since it probes the foundation of ferroelectricity. In this letter, we study a resistor-ferroelectric capacitor (R-FeC) network through a series of coupled equations based on Kirchhoff's law, Electrostatics, and Landau theory. We show that transient NC in a R-FeC circuit originates from the mismatch between rate of free… Expand

Inversion Charge Boost and Transient Steep-Slope Induced by Free-Charge-Polarization Mismatch in a Ferroelectric-Metal–Oxide–Semiconductor Capacitor
It is shown that the key feature of depolarization effect on an FE MOS capacitor in the steady state should be the inversion charge boost, rather than the steep SS (e.g., sub-60 mV/decade at room temperature), which cannot be experimentally observed as the measurement time is much longer than the intrinsic FE response.
