Comparative Photoelectric Characteristics of Nanostructured Pb_(1–x)Sn_xSe Films Obtained by the Codeposition and Layer-by-Layer Deposition of PbSe and SnSe

摘要

Comparative analysis of the photoelectric characteristics of films of the Pb_(0.975)Sn_(0.025)Se solid solution obtained by the hydrochemical codeposition of PbSe and SnSe and the Pb_(0.902)Sn_(0.098)Se solid solution obtained by the layer-by-layer hydrochemical deposition of individual metal selenides (SnSe–PbSe– SnSe–PbSe) with their subsequent heat treatment on air at 523–700 K is performed. It is shown that the films synthesized by layer-by-layer deposition have advantages in terms of their photoelectric characteristics compared with films obtained by codeposition.
