Unveiling the Interfacial Reconstruction Mechanism Enabling Stable Growth of the Delafossite PdCoO₂ on Al₂O₃ and LaAlO₃.

ABSTRACT: Delafossites, composed of noble metal (A⁺) and strongly correlated sublayers (BO₂^-), form natural superlattices with highly anisotropic properties. These properties hold significant promise for various applications, but their exploitation hinges on the successful growth of high-quality thin films on suitable substrates. Unfortunately, the unique lattice geometry of delafossites presents a significant challenge to thin-film fabrication. Different delafossites grow differently, even when deposited on the same substrate, ranging from successful epitaxy to complete growth suppression. These variations often lack a clear correlation to obvious causes like lattice mismatch. Unidentified stabilization mechanisms appear to enable growth in certain cas
