Abstract

Effective negative capacitance has been postulated in ferroelectrics because there is hysteresis in plots of polarization-electric field. In future integrated circuits, the incorporation of negative capacitance into MOSFET gate stacks would reduce the sub-threshold slope, enabling low power operation and reduced self-heating. As a step towards meeting this challenge, effective negative capacitance is demonstrated at room temperature in metal-insulator-metal capacitors, where it is stabilized by the presence of a paraelectric material.
