Nanoscale Dynamics of Superdomain Boundaries in Single-Crystal BaTiO3 Lamellae

Nanoscale Dynamics of Superdomain Boundaries in Single-Crystal BaTiO3 Lamellae

In situ piezoresponse force microscopy (PFM) imaging reveals highly non‐linear kinetics of the superdomain boundary separating two a‐c‐domain bundles in BaTiO3 lamellae. It is suggested that this behavior is caused by an unscreened depolarizing field of newly switched domains that counter balances t...

Zusammenfassung:In situ piezoresponse force microscopy (PFM) imaging reveals highly non‐linear kinetics of the superdomain boundary separating two a‐c‐domain bundles in BaTiO3 lamellae. It is suggested that this behavior is caused by an unscreened depolarizing field of newly switched domains that counter balances the driving force from the applied electric field.
