On the mechanism of room temperature superconductivity in substitutionally doped graphene

A combined mechanism involving phononic and electronic processes is suggested for superconductivity in substitutionally doped graphene. The electronic mechanism is similar to the one used for doped fullerene system, MxC60 (M=K, Rb, etc.) and triggered by bond polarization due to doped impurities such as B or Al. It is found that on increasing the doping, the superconducting critical temperature can be raised to room temperature. tails of the combined model are given along with the predicted values of TC.
