    Abstract: 一開始本實驗重點在研究Cheverel Phase MXMo6S8 (M 為自然界
    存在的元素)超導體上,因其容易形成單一相,這有助於我們將已知
    高溫超導銅氧化物的一些研究方法(如加高壓),應用在這個舊有的硫
    化物超導系統。
    由於我們實驗室不具備有可以在樣品製備過程中加高壓的高溫
    爐,所以採用摻雜不同元素方式,以期達到同樣之效果,將原本不
    具有超導行為而轉變成有超導性或提高其TC。在實驗過程中,我們
    卻發現到新的硫化物超導材料SixMo2S3,其結構為Mo2S3 單一相,
    所以實驗上就以Mo2S3 為主體,摻雜微量之不同元素並比較其差異
    性,同時深入研究準一維的Mo2S3 結構,為何在摻雜Si 原子之後,
    形成超導結構之物理機制。
    At the beginning of the experiment, we focused on Cheveral Phase MXMo6S8 ( M =
    metal), which could easily form the single Cheverel Phase so that we are able to adopt the
    methods used on cuprates to our samples.
    At first MXMo6S8 was doped with suitable amount of foreign elements in order to reach
    the pressure effect for raising Tc or converting non-superconducting materials to
    superconducting one. In the process we found new superconducting compound on
    SixMo2S3-x which is the derivative of Mo2S3. Therefore we shifted our attention on the
    doped quasi-1D compound Mo2S3 and its superconducting properties.
