Investigating Superconducting State Parameters in (TaNb)X(TiZrHf)1−X Compounds: A First Principle Approach Employing MS Excel as Toolkit

This paper employs a first-principle approach to systematically investigate the superconducting state parameters in (TaNb) X (TiZrHf)[Formula: see text] alloys (where X varies from 0 to 1). Utilizing advanced computational techniques, we elucidate the critical factors influencing the superconducting behavior of this mixed-metal system. Our study provides valuable insights into the tuning of critical temperature ([Formula: see text]) and other essential parameters, offering a comprehensive understanding of the superconducting properties. It has been that, due to the simple averaging effect of the individual density of states (DOS) contributions and consistent increase in the electrostatic repulsion between ions, the DOS and Coulomb pseudopotential increase linearly with concentration. The lattice disorder and weak isotope effect affect the electron–phonon coupling strength thereby affecting the critical temperature ([Formula: see text]) of the material. The outcomes contribute to the design and optimization of novel superconductors with potential applications.
