    摘要: 本文重點在研究塊材化合物SiMoS1+x (0≦x≦1)則為MoS2與合金Mo3Si3之混合物,但是在x=0.4時樣品卻成為MoS2與MoSi2之混合物。 SiMoS1+x (0≦x≦1)樣品的常溫電阻率,會隨硫含量的增加而明顯變大,當x = 0, 0.2, 0.8, 1時,樣品分別在4.25、4.41、3.32與3.75K有明顯的電性斜率變化,其中 x = 0與1時,樣品分別在4.54與3.51K有抗磁轉變。並找出三種純相結構MoSi2,MoS2與Mo3Si3。
    In this thesis, the bulk samples SiMoS1+x (0≦x≦1), the polycrystalline structure reveals a poorly-crystalline MoS2 phase with several unknown reflections. However in SiMoS1.4 all of the unknown reflections could be identified to be alloy MoSi2 structure, and it is the only sample which doesn’t show diamagnetic transitions. While in the XRD of the rest samples most of the unknown reflections may be assigned to alloy Mo3Si3 structure. The electrical transitions in resistivity of bulk sample SiMoS1+x with x = 0, 0.2, 0.8, and 1, are observed at 4.25K, 4.41K, 3.32K, and 3.75K, respectively. And the samples with x = 0 and 1, reveal diamagnetic transitions at 4.54K and 3.51K, and find out pure phase of MoSi2, MoS2 and Mo3Si3 .
