Description
Summary:The functional derivative of the superconducting transition temperature T c with respect to the electron-phonon coupling function permits identifying the frequency regions where phonons are most effective in raising T c . This work presents an analysis of temperature effects on the calculation of the δT c / δα 2 F ( ω ) and μ * parameters. The results may permit establishing that the variation of the temperature in the δT c / δα 2 F ( ω ) and μ * parameter allows establishing patterns and conditions that are possibly related to the physical conditions in the superconducting state, with implications on the theoretical estimation of the T c .
