摘要

本文的目的是利用XRD、SEM、EDS和微拉曼光谱等多种技术表征As2S3-Sb2S3-Sb2Te3体系中的多晶和玻璃体相。采用扫描电子显微镜(SEM)、能谱仪(EDS)、x射线衍射仪(XRD)和微拉曼分析对As1.17S2.7Sb0.83Te0.40、As1.04S2.4Sb0.96Te0.60、As0.63S2.7Sb1.37Te0.30和As0.56S2.4Sb1.44Te0.60半导体硫系体玻璃进行了表征。EDS定量分析和测图分析表明，在每个调查区域，鉴定出的元素分别是硫(S)、砷(As)、锑(Sb)和碲(Te)。这些元素在整个样品中以恒定的原子百分比存在，表明样品具有良好的均匀性。通过上述方法对样品的研究表明，样品中存在晶相和非晶相，其中多晶夹杂物对应的结构单元为AsS3、Sb2S3和Sb2Те3。

Structural analysis of As-S-Sb-Te polycrystalline nanostructured semiconductors

The aim of this paper is to characterize the polycrystalline and vitreous phases in the As2S3-Sb2S3-Sb2Te3 systems using several techniques such as XRD, SEM, EDS, and micro-Raman spectroscopy. The As1.17S2.7Sb0.83Te0.40, As1.04S2.4Sb0.96Te0.60, As0.63S2.7Sb1.37Te0.30, and As0.56S2.4Sb1.44Te0.60 semiconductor chalcogenide bulk glasses were examined using Scanning Electron microscopy (SEM), Energy-Dispersive Spectroscopy (EDS), X-Ray diffraction (XRD) and micro-Raman analysis. The EDS quantitative and mapping analysis showed that for each investigated area, the identified elements were sulfur (S), arsenic (As), antimony (Sb) and tellurium (Te). These elements are present in constant atomic percentages on the entire sample, showing a good homogeneity of the samples. The study of samples by the above-mentioned methods showed the presence of crystalline phases and amorphous phases with the polycrystalline inclusions corresponding to the structural units AsS3, Sb2S3, and Sb2Те3.

期刊介绍： Chalcogenide Letters (CHL) has the aim to publish rapidly papers in chalcogenide field of research and appears with twelve issues per year. The journal is open to letters, short communications and breakings news inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in structure, properties and applications, as well as those covering special properties in nano-structured chalcogenides are admitted.
