Variation of in-plane and out-of plane strain as a function of film thickness for the cases of (a) [002]-, (b) [110]- and (c) [111]-oriented grains of the (Ba,Sr)TiO₃ thin films and (d) comparison of lattice parameter (Ba,Sr)TiO₃ grains with different orientations.

Dashed line indicates the bulk value of (Ba,Sr)TiO₃.
