(a) X-ray diffraction pattern (b) topography of PMN-PT/SRO/STO thin film, and (c) x-ray diffraction pattern and (d) topography of thin film.
Domain poling images of the polarized and reverse-poled ( after ) region of the PMN-PT/SRO/STO thin film (a) after , (b) after , and (c) after . Domain poling images of the polarized and reverse-poled ( after ) region of the thin film (d) after , (e) after , and (f) after .
(a) Cross-sectional view of the domain image across the line in Fig. 2(a) and 2(b) cross-sectional view of the domain image across the line in Fig. 2(d). The magnitude of both the single-poled and reversed-poled piezoresponses tends to decrease as time elapses.
Plots of the domain poling relaxation behavior in PMN-PT thin films. (-∎-) represents the reverse-poled region and (-●-) represents the single-poled region of each film. (a) PMN-PT films on SRO/STO substrates and (b) PMN-PT films on substrates. (c) Exponential decay behavior of the PMN-PT/SRO/STO films and (d) films.
