The Study of Superconducting State Parameters of In_(1-x)Tl_x Binary Alloys by Pseudopotential Theory

摘要

The study of the superconducting state parameters (SSP) viz. electron-phonon coupling strength In_(1-x)Tl_x, Coulomb pseudopotential μ~*, transition temperature T_C, isotope effect exponent a and effective interaction strength N_0V of In_(1-x)Tl_x (0 < x < 1) binary alloys have been made extensively in the present work using a model potential. A considerable influence of various exchange and correlation functions on λ. and μ~* is found from the present study. The present results of the SSP are found in qualitative agreement with the available experimental or theoretical data wherever exist.
