Figure 5. Formation mechanism of nitrogen-based superconductors MN6 (M = Sb, Te, I). (A) Calculated Tc and EPC parameter λ at 100 GPa; (B) The superconductivity dependence on pressure of the reported binary superconducting nitrides including SbN6, TeN6, and IN6 proposed in this work; (C) Electronic DOS N(εF) and the content of occupied orbitals in the IPDOS of 5p-block element at Fermi surface. Red and blue spheres represent the 5s, 5p, and 5d orbitals, respectively. EPC: electron-phonon coupling; DOS: density of states; IPDOS: integral projected density of states.
