SUMMARY
The authors observe a giant flexoelectric response in freestanding BiFeO3 and SrTiO3 in their bent state arising from strain gradients up to 3.5 × 107 m-1, suggesting a promising approach for realizing ultra-large polarizations. The simultaneous implementation of strain and straingradient engineering is traditionally subject to the specifications of substrates or epitaxial conditions, which largely restrict the tunability and scalability of strains and strain gradients. The authors observed a huge strain gradient εxx,z arising from a considerable change in the in-plane strain corresponding to variations in lattice spacings a (Figs . . .
