Abstract
The study of the superconducting state parameters (SSP) viz. electron–phonon coupling strength λ, Coulomb pseudopotential μ*, transition temperature T C , isotope effect exponent α and effective interaction strength N0V of In-based binary alloys In 1-x Na x, In 1-x Mg x, In 1-x Zn x, In 1-x Tl x, In 1-x Sn x, In 1-x Pb x and In 1-x Bi x have been made extensively in the present work using a model potential. To explain electron–ion interaction pseudo-alloy-atom (PAA) model is applied for the first time instead of Vegard's Law. A considerable influence of various exchange and correlation functions on λ and μ* is found from the present study. It is also concluded that T C strongly depends on the value of the effective valence Z* of binary alloys.
