摘要

This paper proposes a device incorporating ferroelectric tunnel junction which analyzes the concept of tunneling across a silicon doped hafnium oxide ferroelectric. Variation of electrical parameters with ferroelectric thickness has been examined. Subthreshold swing (SS) of 40 mV/dec has been achieved with ferroelectric thickness of 2 nm. An increasing trend in the I-ON/I-O(FF) ratio is observed with the increase in ferroelectric thickness. Moreover, the impact of temperature (300 K-500 K) on drain current as well as various RF parameter performance such as gate capacitance (C-GG), transconductance (gm), output conductance (g(d)), intrinsic delay, intrinsic gain (g(m)/g(d)), cut off frequency (f(t)) and transconductance frequency product (TFP) has been studied.
