STUDY ON SUPERCONDUCTIVITY OF AMORPHOUS NON-TRANSITION METALS

In this work, the empirical dependances of superconducting parameters and phonon spectrum parameters on the Hall Coefficient,and the problem on the Tc in amorphous non-transition metals are studied. It is found that the relative rise of Tc depends linearly upon the relative increase of λ and the Tc increases with the increase of the cut-off frequency ( ω0 ) of the phonon spectrum. In addition, although the Tc for non-transition metals can be raised by softening phonon spectrum, but there is slim hopes to obtain amorphous superconductor having high Tc for non-transition metals including metal Be. The description of electron properties and strong coupling effects which present in upper critical field Hc2 and energy gaps, 2△0 , of amorphous superconductors are also discussed.
