Pseudopotential in the study of superconducting state parameters of metallic glasses

The superconducting state parameters of glassy superconductors

“…For binary mixtures, the electron-phonon coupling strength, λ, is computed using the relation [3][4][5][6][7][8][9][10][11][12][13][14][15][16]…”

“…The influence of the third element on the electronic and electron transport properties of glassy superconductors has been studied extensively, but its effect on superconducting properties has been given less attention. Only a few researchers have studied the superconducting properties of glassy superconductors using model potential formalism [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

“…The application of pseudopotential to glassy superconductors involves the assumption that pseudoions with average properties are assumed to replace two types of ion in the glassy systems, and a gas of free electrons is assumed to permeate through them. For a successful prediction of the superconducting properties of the glassy alloying systems, a proper selection of pseudopotential and screening function is very much essential [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The theoretical investigation of the SSP of Be-Al glassy superconductors has been reported by Sharma et al [16].…”

“…The pseudo-alloy-atom (PAA) model was used to explain electron-ion interaction in the alloying systems [3][4][5][6][7][8][9][10][11][12][13][14][15].…”

“…where Z, 0 , ε(q) and r C are the valence, atomic volume, H dielectric function and parameter of the model potential of the glassy superconductors, respectively. The parameter of the model potential is determined using the first zero of the form factor [3][4][5][6][7][8][9][10][11][12][13][14][15].…”
