Abstract:

The possibility of symmetrical s-wave superconductivity in the honeycomb lattice is studied within a strongly correlated regime، using the Hubbard model. The superconducting order parameter is defined by introducing the Green function، which is obtained by calculating the density of the electrons ‎. In this study showed that the superconducting order parameter appears in doping interval between 0 and 0. 5، and x=0. 25 is the optimum doping for the s-wave superconductivity in honeycomb lattice.
