ZHONG Guohua at the CAS Shenzhen Institutes of Advanced Technology (SIAT) identified a unique superconducting phase with Tc in the range of 5K-7K for all aromatic hydrocarbons. The origin of a low-Tc phase was ascribed to low density of states at Fermi level induced by about two electrons doping, whereas the high-Tc phase of hydrocarbons with long benzene rings seems to be caused by high density of states at Fermi level upon three-electron doping. The study was published in Frontiers in Physics
