| Research Abstract |
An intercalation of metal atoms into various types of carbon materials was examined using a solution process and an electrochemical process. The Li doped picene shows the superconductivity with a superconducting transition temperature (Tc) as high as 11 K, while the K doped [6]phenacene also shows the Tc of 6 K. Furthermore, the metal-intercalation into graphite was also investigated, which provides the superconducting materials. The highest Tc is now 11.5 K in CaC6, which is the same as that prepared using high-temperature synthesis method with Li/Ca alloy. We tried to make superconducting materials through the intercalation of metal atoms into two-dimensional FeSe crystals, and diverse superconducting materials were successfully produced; the Tc of 46 K is achieved under high pressure. The high-density carrier accumulation into phenacene thin film and crystal was also achieved using electric-double-layer capacitor.
