Electronic structure, electron-phonon interaction and high-temperature superconductivity in V3Si

Using the results of our self-consistent APW band structure calculations, we have calculated the electron-phonon interaction, n⟨I2⟩, the electron mass enhancement factor λ and the superconducting transition temperature T c for V3Si. Our results are in good agreement with the experimental values. In addition we find that the band structure results are a) in good qualitative agreement with the non-self-consistent results of Mattheiss, and b) show no detailed verification for any of the one-dimensional models of the electronic properties of the A15 materials.
