摘要：Using the generalized gradient approximation augmented with maximally localized Wannier functions analysis, we present the formation of cuprate-like electronic structures in Ag^IIF₂–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.
