化学水浴法是目前制备CdS薄膜的主流方法之一,其中对溶液实施不同的溶液激发方式会对薄膜的性能产生很大影响.采用4种不同的溶液激发方式:搅拌法、静置法、超声法、摇晃法以化学水浴法沉积了CdS薄膜.采用台阶仪、X射线衍射仪、扫描电子显微镜和原子力显微镜等系统地研究了这4种不同的溶液激发方式对CdS薄膜的生长速度、晶体结构与表面形貌的影响.实验结果表明,随着沉积时间增加,CdS薄膜的厚度都会逐渐增加并最终趋于一恒定值.搅拌法与摇晃法制备的CdS薄膜具有更快的生长速度、更大的颗粒尺寸以及更加粗糙的表面形貌.采用静置法沉积薄膜在沉积时间较短时,薄膜表面存在大面积的由尺寸12 nm的小颗粒构成的区域.随着沉积时间增加,该区域面积逐渐减小进而消失.通过对薄膜表面形貌随沉积时间增加的演化过程的研究,在一定浓度下CdS薄膜的生长是离子-离子生长机制.通过对比不同溶液激发方式沉积的CdS薄膜的表面形貌,分析了不同溶液激发方式对CdS薄膜形貌的影响.
