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

Several hydrides have been observed high-T c superconductivity under pressure, but a physical-chemical understanding of the properties enhancing T c is still lacking. Here, the authors propose a magnitude named as networking value, combined with hydrogen fraction and the contribution of hydrogen to...

Description
Summary:Several hydrides have been observed high-T c superconductivity under pressure, but a physical-chemical understanding of the properties enhancing T c is still lacking. Here, the authors propose a magnitude named as networking value, combined with hydrogen fraction and the contribution of hydrogen to the density of states at Fermi level, can predict T c of all hydrogen-based compounds with an accuracy of about 60 K.
