Abstract

We have developed a modeling framework to explain the experimentally-observed asymmetric abrupt current jump in DC ID-VG sweeps in ferroelectric FET (FeFET). We demonstrate that: i) with a model that combines the TCAD model for distributed channel and a custom-built physics-based model for ferroelectric (FE) polarization (PFE) switching dynamics, the abrupt current jump during reverse sweep can be reproduced through modeling for the first time; ii) abrupt current jump exists in both forward and reverse sweep, with the forward sweep jump below the instrument noise level and typically not observed; iii) the abrupt jump is due to the significant amount of PFE switching, not due to the formation or rupture of conductive channel path, i.e. percolation.
