Figure 3. Type 3 domain structure. (A) Topography of type 3 domain structure. (B) The corresponding OOP phase signal. (C) The optical image of type 3 domain. (D) IP phase signal measured at a tip-sample orientation of 0. The IP polarization variants are denoted on each domain. (E) The binarized version of (D). (F) IP phase signal measured at a tip-sample orientation of 90. (G) The binarized version of (F). (H) The reconstructed three-dimensional polarization vectors for type 3 domain.
