▎ 摘　　要

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. The details of the combined model are given along with the predicted values of T-c. (C) 2013 Elsevier Ltd. All rights reserved,
