摘要： The disclosed implementations include graphene-based superconductors and methods of producing graphene based superconductors. In particular, in contrast to the inherent electrical characteristics of graphene, in accordance with various implementations graphene is converted to a BCS superconductor, having a critical temperature substantially above zero Kelvin (K), using a combination of charge doping and tensile strain. Charge doping enables enlargement of the Fermi surface of graphene, and tensile strain enables an increase in electron-phonon coupling. For example, a critical temperature T c of 30 K can be achieved by a combination of a doping level of ~3.5x10 14 cm -2 and a strain level of ~16%. In some implementations, a critical temperature T c of 30 K makes graphene-based superconductors commercially viable for a number of industrial applications.
