Abstract

This paper discusses the technology of formation of photoresistive structures based on a composite of lead selenide and lead selenite. The structures are formed by the oxidation of n-PbSe polycrystalline films. Film The surface modification mechanism of n-PbSe films in the oxidation process is analyzed by a Zeiss Merlin scanning electron microscope (SEM). The new results of the authors on the oxidation mechanism of n-PbSe, together with their earlier publications, are summarized and their consistency with each other is examined. A theoretical model (hypothesis) of the potential profile of a photosensitive heterojunction is proposed, in which each crystal of the n-PbSe film during oxidation in an atmosphere of dry air forms a continuous shell on the p-PbSeO₃ surface. The hypothesis on the structural model of the photosensitive heterojunction proposed by other authors, which is based on the oxidation mechanism proposed by us, is practically confirmed in this study.

硒化铅和亚硒酸盐复合材料的光敏性研究

摘要

本文讨论了基于硒化铅和亚硒酸铅复合材料的光阻结构的形成技术。该结构是通过n -PbSe多晶薄膜的氧化形成的。薄膜利用Zeiss Merlin扫描电子显微镜(SEM)分析了n -PbSe薄膜在氧化过程中的表面改性机理。总结了作者关于n -PbSe 氧化机理的新结果以及他们之前发表的文章，并检验了它们之间的一致性。提出了光敏异质结电势分布的理论模型（假设），其中n -PbSe 薄膜的每个晶体在干燥空气气氛中氧化期间在p -PbSeO ₃表面上形成连续的壳。其他作者基于我们提出的氧化机理提出的光敏异质结结构模型的假设在本研究中得到了实际证实。
