Figure 1
(a) PFM phase image of one PZT 2 µm × 2 µm island showing the up (light brown) and down (dark brown) domains, (b) nanodiffraction map over the same region as (a) using integrated intensity of the diffraction pattern obtained near the (002) Bragg peak. A clear difference in intensity is observed between the top and bottom of the image due to the up and down domains. (c) Nanodiffraction map of a selected region in the box which was used for further analysis, (d) and (e) detector images showing the diffraction patterns for the up and down domains, respectively. |
