Sr<sub>1+δ</sub>CrO<sub>3–<i>x</i></sub> Epitaxial Thin Films
Sr1+δCrO3–x epitaxial thin films with −0.14 ≤ δ ≤ 0.14 were grown on SrTiO3(001) substrates by solid-source molecular beam epitaxy (MBE) in codeposition. The impact of the deviation from the cationic stoichiometry (δ) on the structural properties is reported. In spite of a significant in-plane lattice mismatch with the substrate (∼2.25%), all films are epitaxial with flat surfaces, present low mosaicity (∼0.1°), and keep a perovskite-based structure. However, an additional Ruddlesden–Popper (RP) phase is spontaneously formed (n = 2) for δ > 0 (Sr-rich). These results are important for further studies on structure–property relationships in the view to exploit the functional properties of Sr1+δCrO3–x-based films in devices.
