Cobalt-Dimer Nitrides:A Potential Novel Family of High-Temperature Superconductors
文献摘要：
We predict that the square lattice layer formed by[Co2N2]2-diamond-like units can host high-temperature superconductivity.The layer appears in the stable ternary cobalt nitride,BaCo2N2.The electronic physics of the material stems from Co2N2 layers where the dimerized Co pairs form a square lattice.The low energy physics near Fermi energy can be described by an effective two-orbital model.Without considering interlayer couplings,the two orbitals are effectively decoupled.This electronic structure satisfies the"gene"character proposed for unconventional high-temperature superconductors.We predict that the leading superconducting pairing instability is driven from an extended s-wave(s±)to a d-wave by hole doping,e.g.,in Ba1-xKxCo2N2.This study provides a new platform to establish the superconducting mechanism of unconventional high-temperature superconductivity.
