We further performed temperature-dependent optical second harmonic generation (SHG) measurements to explore the strain-induced variation of Tc in the SrTiO3 membranes. But given the experimental strain geometry where the membrane elongates along only one in-plane direction while compresses along the out-of-plane direction due to the Poisson effect (we keep the membrane undeformed along the other orthogonal in-plane direction), the possibility of the tetragonal 4mm point group symmetry is thus ruled out from our analysis.

The PPC coated SrTiO3 film was then released from the substrate and transferred onto a polyimide sheet. d Detailed atomic force microscopy topographic images reveal the crack-free surface of SrTiO3 transferred onto the polyimide sheet. However, due to the limited number of commercially available substrates and defect-induced strain relaxation during growth22, this approach is fundamentally limited in its lack of ability to produce large and continuously tunable strain states.

Fatigue deformation of TiAl base alloys. The ask is for us to move to 100% net-zero and translate commitments into immediate actions thereby delivering actual, measurable decarbonisation and economy-side transformations. For instance, the observed in-plane polarized 180 domain structures in our work with only one in-plane polarization variant (along the [100]/[$\bar 1$00] directions) is rather rare not just in SrTiO3 but also in other ferroelectric perovskites such as PbTiO3, BaTiO3, etc. Rabe, K. & Vasudevan, A.
