Polarization Switching and Domain Wall Motion in Circular and Ring Capacitor Structures in PZT Thin Films

Nava Setter, Ludwig Feigl

Ferroelectric switching in circular and ring capacitors has been performed using a stroboscopic mode of piezoresponse force microscopy. A simple geometric model incorporating the characteristic domain wall motion is sufficient to describe the switching of ...
