ABSTRACT. Hydrogen dense materials of the form AH3 (where A can be Al, Sc, Ga, S, Cr, Se, Y, La, P) are gaining interest with respect to study high temperature superconductivity at pressure with the reach of available techniques. In the present work, we have used first principle calculations to correlate the ionization energies and the superconducting critical temperatures for the metal hydrides. Using a linear regression, a straight line fit of the correlation implies a certain limit for sum of the ionization energy needed for superconductivity to occur. Alkali C60 superconductors shown similar nature with ionization energy.

Keywords: superconductivity, tri hydrides, ionization energies, critical temperature, high pressure
