Modified Transition Temperature Equation for Superconductors

We present the replacement and modification of the Debye temperature θ_D by the average phonon frequency <ω> in the Rowell Solid State Commun. 19 (1976) 1131 linear transition-temperature equation for superconducting materials. We not only improve Rowell's results but also describe the experimental results accurately and consistently for the various superconducting systems which cover the entire range of λ between 0.72 and 2.59. The proposed linear equation of the transition temperature T_C is found to be better and more accurate than those of Jain and Kachhava Can. J. Phys. 58 (1980) 1614.
