I know about the induction of strain in the perovskites material via replacing the smaller cation with a larger one and also know how to generate strain via lattice mismatching between the substrate and perovskite material.
Could someone mention other possible ways for the generation of strain in the perovskites crystal?
Thank you!
Dear Nasir Ali ,
Some unusual lattice strain may also be induced by a synthetic route using an autoclave or any other pressure container, adequately designed for synthesis at higher pressure.

@Nasir Ali,
i think exerting pressure is the cause and inducing strain is its effect.
Dear Nasir Ali ,
You are not only "exerting pressure" into the system; this is not the case. Following a synthetic route under pressure, atoms dislocation, lattice distortion are usually obtained. So, by those phenomenons, strain, and stress are generally retained on the final product, exactly as in substitutional strain and stress it would do.
Best regards,
WNM
