许多作者研究了PbS薄膜光电导特性,正如现有文献指出,PbS薄膜的许多物理特性与薄膜制备方法以及以后制成光电导的工艺过程有关。通过研究不同沉积条件对薄膜晶性的影响证实,当沉积正在进行时把不同量的H_2O_2加进化学溶液,其晶体结构受到很大影响。对这些变化作了系统的x射线衍射分析,所得结果报导如下。 Many authors have studied the photoconductive properties of PbS films. As the literature shows, many of the physical properties of PbS films are related to the fabrication of thin films and the subsequent fabrication of photoconductors. By studying the effect of different deposition conditions on the crystallinity of the films, it was confirmed that different amounts of H 2 O 2 were added into the chemical solution while the deposition was in progress, and the crystal structure was greatly affected. A systematic x-ray diffraction analysis of these changes was made and the results reported are as follows.
