Cuprate-like Electronic Properties in Superlattices with AgIIF2 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 AgII F 2 -related superlattices resulted from the confinement together with structural chemical modification. The out-of-plane electronic reconstruction leads to electron doping of AgF 2 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. © 2014 Macmillan Publishers Limited.
