Abstract

Thin films of nanocrystalline CdS were obtained at the water-toluene interface by reacting cadmium diethyldithiocarbamate in toluene with aq. NaS. Three parameters unique to the topical deposition scheme: the effect of column heights, stirring and the action of molecular surfactants are systematically investigated. The obtained nanocrystalline aggregates are characterized by scanning- and transmission electron microscopy, X-ray diffraction and profilometric measurements. Conditions for obtaining smooth device quality thin films have been identified during these experiments.

摘要

通过使甲苯中的二乙基二硫代氨基甲酸镉与硫化钠水溶液反应，在水 - 甲苯界面获得了纳米晶CdS薄膜。系统研究了局部沉积方案特有的三个参数：柱高的影响、搅拌以及分子表面活性剂的作用。通过扫描电子显微镜、透射电子显微镜、X射线衍射和轮廓测量对所得的纳米晶聚集体进行了表征。在这些实验中确定了获得具有器件质量的光滑薄膜的条件。
