Recently, the interest for the family of low dimensional materials has increased significantly due to the anisotropic nature of their fundamental properties. Among them, antimony sulfide (SbS) is considered a suitable material for various solid-state devices. Although the main advantages and physicochemical properties of SbS are known, some doubtful information remains in literature and methodologies to easily assess its critical properties are missing. In this study, an advanced characterization of several types of SbS samples, involving the Rietveld refinement of structural properties, and Raman spectroscopy analysis, completed with lattice dynamics investigations reveal important insights into the structural and vibrational characteristics of the material. Based on the gathered data, fast, non-destructive, and non-invasive methodologies for assessment of the crystallographic orientation and point defect concentration of SbS are proposed. With a high resolution in-sample and assessment, these methodologies will serve for accelerating the research and application of SbS in the research field.
最近,由于低维材料基本性质的各向异性,人们对这类材料的兴趣显著增加。其中,硫化锑(SbS)被认为是适用于各种固态器件的材料。尽管SbS的主要优点和物理化学性质是已知的,但文献中仍存在一些可疑信息,且缺少易于评估其关键性质的方法。在本研究中,对几种类型的SbS样品进行了先进的表征,包括对结构性质的Rietveld精修以及拉曼光谱分析,并结合晶格动力学研究,揭示了该材料结构和振动特性的重要见解。基于收集到的数据,提出了用于评估SbS晶体取向和点缺陷浓度的快速、无损和非侵入性方法。这些方法具有高分辨率的样品内和评估能力,将有助于加速SbS在研究领域的研究和应用。
