摘要：

We present a theoretical model study of superconductivity for iron-based high-T-c superconductors in s(+/-)-wave symmetry, considering two degenerate orbitals and the electron hopping up to the third nearest neighbor as a two-orbital model. The analytic expression for the temperature dependence of the superconducting order parameter is derived by Zubarev's technique of double time single particle Green's function method and solved self-consistently. The effect of inter orbital hopping on the superconducting energy gap parameter and electronic specificheat is studied.
