Figure 13. Thickness dependence of ferroelectric/ferroelastic domain switching under electric biasing. (A) Dark-field TEM images of thick TEM samples under the electric field. Yellow regions indicate the 180° domain switched regions. (B) Dark-field TEM images of thin TEM samples under the electric field. Pink regions indicate the 90° domain switched regions.
