  The study investigates the influence of negative capacitance on the transfer
characteristics of vdW FETs on the heterophase of CIPS ferroelectric. Notably,
a less pronounced NC resulting from the spatial distribution of the
ferroelectric and paraelectric phases plays crucial role in stabilizing of
n-channel-conductance. This results into the emergence of a non-volatile logic
state, between the two binary states of TFETs. Concerned study proposed
NC-TFETs based on ferroionic crystals as promising devices for generating a
stable logic state below Vth.
