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. — Figure 1 from Seungbum Hong et al. “Ferroelectric Domain Studies of

NanoWorld EFM PtIr coated probes were used for the PFM measurements mentioned in this brand new publication on ferroelectric domain imaging of patterned BFO thin films in Scientific Reports.

Congratulations to the authors!
