摘要
本研究探讨了溶液法制备的二硫化钼（MoS2）薄膜的光学和结构特性。通过化学剥落合成二硫化钼，并使用旋转涂层技术沉积在熔融二氧化硅和硅衬底上。利用扫描电子显微镜和原子力显微镜对膜的形貌和结构特性进行了表征。通过紫外-可见光谱和拉曼光谱检测其光学性质。结果表明，MoS2薄膜在400 ~ 710 nm之间具有1.40 eV的间接带隙，吸收率超过60%。此外，基于物理的光学模型预测，在MoS2完全覆盖的情况下，潜在电流产生为25 mA cm−2，这表明溶液处理的MoS2作为光电应用中的吸收层具有重要潜力。
Optical Properties of Spin-Coated Solution Processed MoS2
In this study, the optical and structural properties of solution-processed molybdenum disulfide (MoS2) thin films are explored. MoS2 is synthesized via chemical exfoliation and deposited on fused silica and silicon substrates using a spin-coating technique. The morphology and structural properties of the films are characterized using scanning electron microscopy and atomic force microscopy. Optical properties are examined through UV–vis and Raman spectroscopy. In the results, it is shown that the MoS2 thin films exhibit an indirect bandgap of 1.40 eV with over 60% absorption between 400 and 710 nm. Also, physics-based optical modeling predicts a potential current generation of 25 mA cm−2 with full coverage of MoS2, indicating significant potential for solution-processed MoS2 as an absorber layer in optoelectronic applications.
