| Abstract: | According to the theory of BCS, Cooper pairs were the foundation of superconductivity. In this paper, at the base of BCS theory we study the MgB 2 superconductivity from the structure of MgB 2, we made use of the Tight-binding approximation theory to explain the MgB 2 superconductivity and got a reasonable result. |
