Planar capacitor structures formed by a ferroelectric film embedded between two electrodes are used to investigate the details of polarization switching. Scanning probe microscopy is used to observe the domain growth from one electrode to the other during the capacitor switching. Studies of the kinetics of domain evolution allows clear visualization of nucleation sites, as well as forward and lateral growth stages of domain formation.
