Device Structural Effects on Negative-Capacitance FETs

Abstract

This paper discusses several device structural effects on negative-capacitance FETs (NCFETs) with emphasis on the wide-range average subthreshold swing. We point out and explain the intrinsic difference between SOI and double-gate 2D NCFETs. The impact of drain coupling on the NC effect and its implication on the design of short-channel NC-FinFETs are also addressed.
