![Figure 1 from "Ferroelectric Domain Studies of Patterned (001) BiFeO 3 by Angle- Resolved Piezoresponse Force Microscopy": Patterned mesas are separated from the continuous film by lithography, as shown in the AFM topography image. (b) Schematic drawing of the atomic structure of BFO with angle-resolved polarization models. The Fe (red sphere) atom can be displaced towards twelve possible polarization orientations with respect to its centrosymmetric position. (c) AR-PFM domain map of a 1.2 × 1.2 μm2 area of unpatterned BFO film, corresponding to the black dashed area in (a). (d) The area distribution of each polarization variant according to angle relative to the [100] direction. (e) The average area of stable and meta-stable polarization variants.](https://dhipgo7nn2tea.cloudfront.net/wp-content/uploads/2018/01/10172613/Figure_1_from_Ferroelectric_Domain_Studies.jpg)
