摘要: We study the effects of the variation of ferroelectric material properties (thickness, polarization, and coercivity) on the performance of negative capacitance FETs (NCFETs). Based on this, we propose the concept of conservative design of NCFETs, where any unintentional yet reasonable and simultaneous variation (similar to +/- 3%) in ferroelectric parameters does not result in the emergence of hysteresis and causes only a reasonable variation in the ON-current (<= 5%) and, within these constraints, the enhancement of ON-current due to the addition of the ferroelectric gate oxide, which is is maximized.
