“…If graphene is on a metal surface, electron-electron interaction is considerably reduced due to screening by the substrate 10 . Regarding EPC, superconductivity in graphene has not been reported experimentally yet, despite EPC induced superconductivity was found in many other carbonrelated materials like intercalated graphite (GIC) 11 , fullerene crystals [12][13][14][15] , nanotubes 16 and boron-doped diamond 17 . In these systems, the common way to achieve superconductivity is electron doping that enlarges the Fermi surface and hence the phase space contributing to EPC, leading to an enhanced T c .…”

“…[1][2][3][4][5][6] For example, alkali metal intercalation into solid C60 produces A3C60 superconductors, with Tc as high as 38 K for Cs3C60 at 7 kbar. 6 In these materials, cations occupy the interstitial voids that already exist in the host e.g., in the fcc lattice of C60 (Figure 1).…”

“…Only in 1991 was it shown that alkali-doped C 60 exhibits SC with maximum T c of 33 K. 8 It was the first representative of a threedimensional ͑3D͒ carbon-based metal with a modified ͑com-pared to graphite͒ coupling of lattice vibrations to the conduction electrons due to the curvature of the molecule but still with -band derived states at the Fermi level.…”

“…The search for high-temperature superconductivity in carbon phases started in 1965 when T c ϭ0.55 K in KC 8 was reported, and SC was subsequently explained in terms of the interaction of -derived bands with the longitudinal phonon modes of the graphite layer. 5 Similar conclusions for the electronic structure at the Fermi level were derived for another GIC, LiC 6 .…”
