Abstract
The effects of surface morphology on domain formation and relaxation in ferroelectric materials have been investigated. Comparison of the topography of triglycine sulfate with its ferroelectric domain image reveals a deterministic behavior in the formation of the equilibrium domain configuration. It is observed that defects such as crystal imperfections, cleavage steps and strained lines make ferroelectric state more stable by suppressing short-range repulsion, which results in domain pinning. On the other hand, it can be seen that long-range interaction is screened by free carriers in the metallic film. For this reason, we can see the domain movement beneath the metallic film is faster than that in bare surface.
