From: Strong correlation between electronic bonding network and critical temperature in hydrogen-based superconductors

Fig. 4

The upper panel shows the ELF isosurface and the three dimensional network spanning through all the crystal, which is formed by the ELF saddle points and the atoms, associated with the ϕ value for PdH(70), YH4(15), and H3S(138). The networking value is given for each case. The bottom panels show the critical temperature Tc as a function of the networking value ϕ (left), the networking value multiplied by Hf (center), Φ = ϕHf, and the networking value multiplied by Hf and the cubic root of the fraction of the DOS at the Fermi energy coming from the hydrogen atoms HDOS, \({{{\Phi }}}_{{{{{{{{\rm{DOS}}}}}}}}}=\phi {H}_{f}\root 3 \of {{H}_{{{{{{{{\rm{DOS}}}}}}}}}}\) (right). The dotted line in the last panel represents a fit for which Tc = (750ΦDOS − 85) K which is able to estimate Tc within 60 K.
