Negative Capacitance: Exploiting Stored Energy in Ferroelectric Materials to Break Fundamental Barriers of Energy Efficiency in Electronic Devices

In 2008, we theoretically predicted that it could be possible to stabilize a ferroelectric material at a state of negative differential capacitance, which when used as a gate insulator in a MOSFET, could reduce the subthreshold swing below the otherwise fundamental 60 mV/decade. Reducing the swing below 60mV/decade means that the overall supply voltage and power dissipation could be reduced significantly. The difference of this concept with other existing proposals to reduce the subtheshold swing in MOSFETs is that the mechanism of electron transport remains unchanged and therefore the speed of operation does not need to be traded off for lower energy dissipation. In the recent years, multiple experimental demonstration have established this concept from both fundamental and technological point of view. In this talk, I shall discuss the conceptual background and recent experimental studies regarding this concept. I shall also discuss challenges and open questions as we currently see them.
