Hydrochemical synthesis of thin films of mercury chalcogenides (HgS and HgSe): A brief review.

The main aspects of mercury sulfide and mercury selenide thin film synthesis using the chemical deposition method are considered. An analysis of various factors affecting film properties was conducted, including the study of how the nature of the substrate and its pretreatment influence film properties. The effects of the working solution's temperature, deposition time, and annealing conditions on film characteristics were investigated. The impact of these parameters on the phase composition, and optical, electrical, and morphological properties of the films, is discussed and summarized. The review also explains how the choice and concentration of initial reagents affect the obtained films' parameters, characteristics, and properties.
