    研究成果名稱(英):Superconductivity in the PbO-type structure -FeSe
    簡要記述(中):繼1987年發現超過絕對溫標77度的YBa2Cu3O7- 超導體之後,物理研究所的超導體研究團隊於2008年再度創新發現一種結構更簡單、更安全無毒、更容易製造的「鐵基超導體」(FeSe),提供高溫超導研究新材料。超導領域科學家一直認為,只有像銅氧化物這類反鐵磁絕緣體才能成為高溫超導體,而最近發表的這種氧化鉛結構的鐵硒化合物「PbO type structure α-FeSe」,目前的超導轉變溫度為絕對溫度30K,再次以精彩的實驗,顛覆以往大家深信不疑的高溫超導反鐵磁信仰。以如同當年發現高於液氮溫度的YBa2Cu3O7- 超導體,大大提升超導的應用價值;這次的無毒性鐵化硒超導體的發現,可讓更多團隊很快進入此領域,並且提供了高溫超導理論一個嶄新的發展線索,更進一步邁向室溫超導之夢想。「鐵基超導體(FeAsLaO1-xFx)」首次由東京工業大學細野英夫教授的團隊在2008年初發現[1],推翻磁性材料不可能超導的假設。這個發現具有雙重意義:
    一、 銅基超導材料的超導轉變溫度在提高到絕對溫度138 度後已經很難提升,需要另覓其他能在室溫下運作的材料;
    二、 鐵的蘊藏量遠高於銅,在所有金屬中居第四位,比銅更容易取得。

    簡要記述(英):Prof. Maw-Kuen Wu’s group, at the AS-IOP, discovered that the iron selenide (FeSe) compound with tetragonal symmetry showed superconducting transition at 8 K. This compound is a member of the new Fe-based superconductor family, which was discovered last year that showed relatively high transition temperature. The crystal structure of iron selenide is the simplest among all member of Fe-based superconductors. It provides a direct probe of the correlation between observed superconducting properties with the crystal structure. Detailed structural investigations of this new compound showed that a low temperature distortion, from tetragonal to monoclinic symmetry as shown in the figure, is directly correlated with the occurrence of superconductivity. This important findings were first published in the 23 September 2008 issue of Proc. Natl. Acad. Sci. USA
