Abstract Authors report the synthesis of PdSe2-xSx solid-solutions (0 ≤ x ≤ 0.86) with pentagonal layered structure and their transport properties. From structural and optical characterizations, it can be confirmed that S atoms are successfully substituted on Se-site in the parent phase of PdSe2. By analyzing the electrical and thermal transport characteristics, it reveals that the density of states effective mass as well as band gap of PdSe2-xSx can be controlled by varying x. It strongly suggests that S substitution can be an effective compositional tuning approach for engineering the electronic band structure in pentagonal layered PdSe2 system.

五边形层状PdSe2-S固溶体的组成效应及其传输特性

摘要 作者报告了具有五边形层状结构的 PdSe2-xSx 固溶体 (0 ≤ x ≤ 0.86) 的合成及其传输特性。从结构和光学表征可以证实，在 PdSe2 母相中的 Se 位上成功取代了 S 原子。通过分析电和热传输特性，它揭示了 PdSe2-xSx 的态密度有效质量和带隙可以通过改变 x 来控制。这强烈表明 S 取代可以是一种有效的成分调谐方法，用于在五边形层状 PdSe2 系统中设计电子能带结构。
