Abstract

CONCENTRATION DEPENDENCE OF SUPERCONDUCTING STATE PARAMETER: A FIRST PRINCIPLE STUDY

Ashwani Kumar*

ABSTRACT

In the present manuscript the concentration dependent study of superconducting state parameters viz., Coulomb pseudopotential ?*, electron – phonon coupling strength ?, SC transition temperature TC, interaction strength NOV, semi band gap ?, energy or mass renormalization parameter Z0 and isotope effect exponent ? have been studied. Harrison?s First Principle pseudopotential (HFPP) technique in conjunction with BCS theory and McMillan?s formalism has been used in the present investigation. Reasonable agreement with theoretical and experimental data has been obtained.
