摘要: 合成了具有钙钛矿结构的有机-无机复合层状半导体材料，(C₁₂H₂₅NH₃)₂SnI₄。测得其电导率为5×10^-3S·cm^-1。粉末X-射线衍射(XRD)结果表明在有机层中的烷基链间有较高的链交叉。用示差扫描量热法(DSC)，变温拉曼光谱(Raman)和变温红外光谱(IR)研究了其微观结构随温度的变化。

Abstract: A novel hybrid semiconductor，(C₁₂H₂₅NH₃)₂SnI₄ with layered organic-inorganic perovskite structure， was chemically synthesized. Its conductivity was measured to be 5×10^-3S·cm^-1. The results of XRD showed its structural feature was high interdigitation of alkyl chains at organic layers. The temperature dependence of the structure of the hybrid semiconductor has been studied by DSC， microscopic Raman and FT-infrared spectro-scopies.

Keywords: organic-inorganic hybrid layered semiconductor perovskite Raman tin(Ⅱ) iodide phase transition
