The surface micromorphology and roughening of the thermal evaporation-coated FTO/ZnS bilayer thin films annealed at 300, 400, 500, and for 1 h have been studied. AFM images of the prepared samples were analysed by the MountainsMap software, and the effects of the annealing temperature on the surface texture of the FTO/ZnS thin film's surface were investigated. Stereometric and advanced fractal analyses showed that the sample annealed at exhibited greater surface roughness and greater skewness and kurtosis. This film also has the most isotropic surface and exhibits the highest degree of heterogeneity. Also, despite the decrease in surface roughness with increasing temperature from 500 to , the fractal dimension tends to increase. The static water contact angle measurements indicate that the film annealed at exhibits higher hydrophobicity, which can be attributed to its greater topographic roughness. Our research indicates that the surface morphology of FTO/ZnS bilayer thin films is influenced by the annealing temperature. Changing factors such as roughness, fractality, and wettability parameters to help improve surface performance make the FTO/ZnS bilayer suitable for application in electronic and solar systems.
研究了在300、400、500℃退火1小时的热蒸发镀膜FTO/ZnS双层薄膜的表面微观形貌和粗糙度。用MountainsMap软件分析制备样品的原子力显微镜（AFM）图像，并研究退火温度对FTO/ZnS薄膜表面纹理的影响。立体测量和高级分形分析表明，在[具体温度]退火的样品具有更大的表面粗糙度、更大的偏度和峰度。该薄膜还具有最各向同性的表面，并表现出最高程度的不均匀性。此外，尽管从500℃到[另一温度]随着温度升高表面粗糙度降低，但分形维数趋于增加。静态水接触角测量表明，在[具体温度]退火的薄膜表现出更高的疏水性，这可归因于其更大的形貌粗糙度。我们的研究表明，FTO/ZnS双层薄膜的表面形态受退火温度影响。改变粗糙度、分形性和润湿性参数等因素以帮助改善表面性能，使得FTO/ZnS双层适用于电子和太阳能系统。
