Cuprate-like electronic properties in superlattices with Ag(II)F₂ square sheet.

ABSTRACT: Using the generalized gradient approximation augmented with maximally localized Wannier functions analysis, we present the formation of cuprate-like electronic structures in Ag(II)F2-related superlattices resulted from the confinement together with structural chemical modification. The out-of-plane electronic reconstruction leads to electron doping of AgF2 plane and gradually destablizes the antiferromagnetic state. Eventually a stable nonmagnetic metallic state emerges by applying in-plane tensile strain, in which the shape of effective Fermi surface of AgF2 plane exhibits the key feature of high-temperature cuprate superconductor.
