Apr 2014   層状カルコゲナイド物質への電気化学的インターカレーションによる新超伝導物質創製
 超伝導物質は、低温にて電気抵抗がゼロを示すため、将来のエネルギー輸送を担う材料として期待されている。しかしながら、その超伝導になる温度は、室温には達しておらず新たな超伝導物質開拓が必要である。近年、鉄カルコゲナイド超伝導物質は、その単純な層状構造と高い超伝導転移温度をもつことから非常に注目されている。特に、カルコゲナイド層間への化学的インターカレーションにより超伝導転移温度が上昇することが数多く報告されている。そこで本研究では、層状カルコゲナイド物質に着目し、電気化学的なインターカレーションにより新超伝導物質を創製する。
