Fig. 8: Energy barriers for polarization switching in Sr3Sn2O7.
From: Suppressing the ferroelectric switching barrier in hybrid improper ferroelectrics
a The energy barriers of different pathways for unstrained Sr3Sn2O7. The horizontal axis is the “reaction coordinate” that parametrizes the switching path. Arrows indicate the barrier heights. b The energy of the Pn*am pathway in Sr3Sn2O7, as a function of tensile biaxial strain.
