Figure 7. Phase structure evolutions of (110)-oriented PTO films with respective to misfit strain ε₂₂ at various constant strains ε₁₁. (A-C) ε₁₁ = -2%; (D-F) ε₁₁ = 0%; (G-I) ε₁₁ = 2%. (A, D, G) are the volume fractions. (B, E, H) are the polarization components of various phases. (C, F, I) are the angle θ between the polarizations of the M_c(O_c) phase and the x₃ axis, in which the bars represent the standard deviations of the angle.
