Electronic and Superconductivity Properties of FeSe Superconductor
We have investigated theoretically electronic and superconducting properties of FeSe superconductor. The calculated specific heat effective mass is found m*/mband = 2.15. This result is comparable with angle resolved photoemission spectroscopy data with the other Fe-pnictdes compound. The electron-phonon coupling constant is found l = 0.7 for this superconductor. This result is also comparable with the results of linearized augmented plane wave method. It is observed that the FeSesystem is more correlated system compared to the Fe element.
