Cobalt-dimer Nitrides -- a Potential Novel Family of High Temperature Superconductors

Yuhao Gu, Kun Jiang, Xianxian Wu +1

We predict that the square lattice layer formed by [Co${}_2$N${}_2$]${}^{2-}$ diamond-like units can host high temperature superconductivity. The layer appears in the stable ternary coba…
