アルカリ金属塩化物フラックスを用いた層状ダイカルコゲナイド超伝導体の単結晶育成

抄録

  Layered dichalcogenide superconducting single crystals were grown by the flux method using alkali metal chloride flux. Particularly, cesium chloride (CsCl) is a powerful flux for the growth of chalcogenide materials single crystals. In this paper, the focus was on the superconductors of BiS₂-based and misfit layered compounds single crystals. Those grown single crystals were plate-like in shape, with a size of 1-2 mm and a thickness of 10-100 μm. Additionally, the single-crystal growth method using a reduction agent was introduced for the alkali metal intercalated layered dichalcogenide. The alkali metal intercalated into the layered dichalcogenide single crystals was obtained from the flux using Cd metal, which was the reduction agent.
