Abstract
The superconductivity of Rhenium Beryllium in two band model is theoretically studied using a standard model Hamiltonian which contains the Bardeen, Cooper and Schriefer, BCS type pairing interaction. Green function formalism was employed to obtain expression for superconducting order parameter in the bands, the coupling parameters and the superconducting critical temperature, T C , for this ReBe22 material. Our findings indicate, the enhancement of the superconducting critical temperature with the augmentation of the electron-phonon coupling strength in the entire system. The variation of the coupling parameter in the bands is understood as the reason for introducing a temperature gap and rising of the critical temperature suggesting significant upsurge at further scrutiny.
