论文摘要
使用高压合成合成了五个不同的M = Ag，CD，SN，SB，PB和BI的高透镜合金式Thirurides M-TE。结构表征表明，所有获得的样品均具有立方NaCl型结构。六个样本，即agcdsnsbpbte5，aginsnsbpbte5，agcdinsnsbte5，agcdsnpbbite5，agcdinpbbite5和agcdinsnbite5显示超导性。这些样品中最高的过渡温度（TC）为1.4 k，对于aginsnsbpbte5。 AGCDINSBPBTE5样品显示出半导体样的运输行为。从TC和晶格常数之间的关系中，发现对于较大的晶格常数的牙尿酸盐可以观察到较高的TC。
High-entropy-alloy-type tellurides M-Te, which contain five different metals of M = Ag, In, Cd, Sn, Sb, Pb, and Bi, were synthesized using high pressure synthesis. Structural characterization revealed that all the obtained samples have a cubic NaCl-type structure. Six samples, namely AgCdSnSbPbTe5, AgInSnSbPbTe5, AgCdInSnSbTe5, AgCdSnPbBiTe5, AgCdInPbBiTe5, and AgCdInSnBiTe5 showed superconductivity. The highest transition temperature (Tc) among those samples was 1.4 K for AgInSnSbPbTe5. A sample of AgCdInSbPbTe5 showed a semiconductor-like transport behavior. From the relationship between Tc and lattice constant, it was found that a higher Tc is observed for a telluride with a larger lattice constant.
