Figure 8. (A and G) In situ SEM images of the BTO nano-spring in compressive and tensile deformation, respectively. (B-F and H-L) Distribution of the strain component εzz, the domain structure, the outer surface domain, the inner surface domain, and the polarization component Pθ and strain distribution εθ along the middle line of the outer surface of the BTO nano-spring during compression and stretching, respectively.
