Abstract

We present the results of the study of the microstructure, X-ray diffraction and Raman scattering spectra of Cu2SnS3 (CTS) films synthesized at 500 o C by the sulfurization of SnCu stacked metal precursors with different annealing time. The results indicate that sulfurization time has a great influence on both composition and morphology of the film. It is shown that the process of formation of a single-phase CTS compound with a monoclinic structure and composition close to stoichiometry is completed for a synthesis time of 60 - 80 min. With an increase in the time of synthesis to 120 min, the preservation of the monoclinic structural modification of the material is observed, accompanied by a shift in the stoichiometric composition, namely copper enrichment, material delamination and degradation of microstructural characteristics. As a result, it was found that the most optimal conditions for the synthesis of a single-phase Cu2SnS3 compound of a monoclinic structure are the temperature 500 o С with the duration of the sulfurization process from 60 to 80 min.

研究通过磁控溅射沉积金属前驱体硫化制备的 Cu2SnS3 薄膜的微观结构

我们介绍了对锡铜叠层金属前驱体在 500 o C 温度下硫化合成的 Cu2SnS3 (CTS) 薄膜的微观结构、X 射线衍射和拉曼散射光谱的研究结果。结果表明，硫化时间对薄膜的成分和形态都有很大影响。结果表明，单相 CTS 化合物的形成过程在合成时间为 60 - 80 分钟时完成，该化合物具有单斜结构，成分接近于化学计量学。随着合成时间延长至 120 分钟，材料的单斜结构改性得以保留，同时化学计量成分发生变化，即铜富集、材料分层和微观结构特征退化。结果发现，合成单相 Cu2SnS3 单斜结构化合物的最佳条件是温度为 500 ℃，硫化过程持续时间为 60 至 80 分钟。
