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.

使用溶液工艺和电化学过程检查了金属原子与各种类型的碳材料的插入。 Li掺杂的picene显示了超导过渡温度（TC）高达11 K的超导性，而K掺杂[6]苯乙烯也显示了6 K的Tc。现在，最高的TC是CAC6中的11.5 K，与使用LI/CA合金使用高温合成方法制备的TC相同。我们试图通过将金属原子插入到二维FESE晶体中制造超导材料，并成功生产了多种超导材料。在高压下实现46 K的TC。还使用电动双层电容器来实现高密度载体积累到苯乙烯薄膜和晶体中。
