Abstract

Sb_xSe_y thin-films were deposited by chemical-molecular beam deposition (CMBD) on soda-lime glass from antimony (Sb) and selenium (Se) precursors. Due to the separate control of Sb (between 980 and 1025°C) and Se (between 415 and 470°C) source temperature, thin films of antimony selenide with different component ratios carry out obtained. The investigation encompassed a comprehensive analysis of the elemental and phase composition, like the crystal structure, of Sb_xSe_y films. To achieve this, a combination of analytical techniques was employed, including energy-dispersive X-ray microanalysis, atomic force microscopy, Raman spectroscopy, X-ray diffraction, and scanning electron microscopy. The bandgap of the films was ascertained in the region 1.03–1.25 eV through the acquisition of absorption spectra using a spectrophotometer. This enabled the determination of the films’ optical properties and facilitated further analysis of their potential applications. The physical properties of Sb_xSe_y films with various ratio were researched.

在 400°C 基底温度下获得的 SbxSey 薄膜的结构和光学特性

摘要以锑（Sb）和硒（Se）为前驱体，通过化学分子束沉积法（CMBD）在钠钙玻璃上沉积了锑硒薄膜。通过分别控制锑（980 至 1025°C）和硒（415 至 470°C）的源温度，获得了不同成分比例的硒化锑薄膜。这项研究包括对 SbxSey 薄膜的元素和相组成以及晶体结构的全面分析。为此，研究人员采用了多种分析技术，包括能量色散 X 射线显微分析、原子力显微镜、拉曼光谱、X 射线衍射和扫描电子显微镜。通过使用分光光度计获取吸收光谱，确定了薄膜的带隙在 1.03-1.25 eV 之间。这有助于确定薄膜的光学特性，并进一步分析其潜在应用。研究了不同比例的 SbxSey 薄膜的物理性质。
