Emergence of superconductivity in doped glassy-carbon

Glassy carbon (GC), a non-graphitizing carbon which combines glassy and ceramic properties with those of graphite, have been doped to superconductors. The KGC8 presents Tc around 7.98 K is about dozens of times larger than that of potassium doped GIC. The results demonstrate that doped glass carbons are good model materials for studying the mechanism of superconductivity in carbon-based materials. Furthermore, to our best knowledge, it is the first time to get the superconductor from the polymer precursor.
