Fig. 3: Electronic and superconducting properties of M2AuB6.
From: Ambient-pressure superconductivity in covalent Au-B frameworks stabilized by electropositive metals
Ca2AuB6 at ambient pressure: a projected electronic band structure, b Fermi surfaces with the color drawn proportional to the magnitude of the Fermi velocity, and c Fermi surface nesting function, ξ(Q). Na2AuB6 at ambient pressure: d projected electronic band structure, e Fermi surfaces with the color drawn proportional to the magnitude of the Fermi velocity, f Fermi surface nesting function, ξ(Q), and g phonon dispersions weighted by the magnitude of the electron−phonon coupling EPC (λqv), projected phonon density (PHDOS), Eliashberg spectral function, α2F(ω), and EPC integral, λ(ω). h Phonon vibration modes for E-1 and B2g modes, with the red arrows on the atoms indicating the direction of their vibrations. i Calculated Tc, λ, and −ICOHP values of Au−B bond for K2AuB6 and Na2AuB6 at ambient pressure.
