Abstract

The effect of the ratio of CdS and PbS components on the surface morphology, optical and photoelectric characteristics of films obtained by hydrochemical deposition has been studied. It is shown that, depending on the predominance of CdS or PbS in the film, the surface morphology changes significantly, which correlates with changes in the optical and photoelectric characteristics. An increase in the stability of photoelectric characteristics is demonstrated only by samples with a predominance of CdS. When PbS predominates, photoquenching and slow relaxation of the dark current after illumination are observed.

异质 CdS-PbS 材料中的成分比例对光电特性及其随时间变化稳定性的影响

摘要研究了 CdS 和 PbS 成分比例对通过水化学沉积获得的薄膜的表面形貌、光学和光电特性的影响。研究表明，根据薄膜中 CdS 或 PbS 所占比例的不同，表面形貌会发生显著变化，这与光学和光电特性的变化相关。只有 CdS 占主导地位的样品才能显示出光电特性稳定性的提高。当 PbS 占主导地位时，会观察到光淬灭和照明后暗电流的缓慢松弛。
