Negative Capacitance Effect
In the last couple of years many groups have independently demonstrated the negative capacitance effect and <60 nV/decade subthreshold swing in transistors. In this talk I will discuss our most recent results and understanding of the negative capacitance effect that were developed in part by our research in the STARNET/LEAST center. Specifically, I shall discuss questions that has often come up such as: (i) effect of domains (ii) effect of domain nucleation vs domain growth (iii) differential vs absolute voltage amplification (iii) DC vs time-dependent behavior and (iV) speed. I shall also discuss how age-old approximations in the standard form of Landau-Khalatnikov equations, conventionally used in the analysis of negative capacitance effect, have led to certain confusions.
