Investigation of the Impact of Externally Applied Out-of-Plane Stress on Ferroelectric FET

Polarization switching and AC small-signal capacitance in Ferroelectric Tunnel Junctions

“…Experimental characterization and sound modelling are both paramount for an optimal design of ferroelectric devices. The multi-domain Landau, Ginzburg, Devonshire (LGD) theory is well credited for the ferroelectric dynamics, and it has been used for negative capacitance effects [5]- [9], as well as for the operation of FTJs [10] and of FeFETs [11]. The most appropriate thermodynamic potential in the presence of free charges in the dielectric stack has been recently revisited in [12].…”
