论文摘要
高压技术在广泛的研究领域开放对功能材料的探索。具有硼掺杂的钻石加热器和运输测量端子的已建立的钻石砧室已执行了立方SN $ _ {3} $ s $ _ {4} $超导体的高压合成。 X射线衍射和拉曼光谱表明SN $ _ {3} $ S $ _ {4} $相位在减压过程中P> 5 GPA的压力范围内稳定。钻石砧细胞中的传输测量端子检测合成的SN $ _ {3} $ s $ _ {4} $中的金属性质和超导性,最大发作过渡温度为13.3 k,在5.6 GPA时为13.3 k。观察到的压力-T $ _ {C} $关系与第一原理计算中的关系一致。 SN $ _ {3} $ S $ _ {4} $中超导性的观察在高温和压力条件下打开了更多的材料探索。
High-pressure techniques open exploration of functional materials in broad research fields. An established diamond anvil cell with a boron-doped diamond heater and transport measurement terminals has performed the high-pressure synthesis of a cubic Sn$_{3}$S$_{4}$ superconductor. X-ray diffraction and Raman spectroscopy reveal that the Sn$_{3}$S$_{4}$ phase is stable in the pressure range of P>5 GPa in a decompression process. Transport measurement terminals in the diamond anvil cell detect a metallic nature and superconductivity in the synthesized Sn$_{3}$S$_{4}$ with a maximum onset transition temperature of 13.3 K at 5.6 GPa. The observed pressure-T$_{c}$ relationship is consistent with that from the first-principles calculation. The observation of superconductivity in Sn$_{3}$S$_{4}$ opens further materials exploration under high temperature and pressure conditions.
