Annealing effect on temperature stability and mechanical stress at the “CdxPb1−xS film – substrate” interface

The article establishes the upper temperature steadiness limit of СdxPb1-xS supersaturated solid solutions obtained by chemical bath deposition. СdxPb1-xS (x = 0.06; 0.122; 0.176) and (x = 0.02–0.05) films remained stable under the heating up to 405–410 and 450 K, respectively. SEM studies have shown that heating of СdxPb1-xS films (x = 0.02–0.05) to 620 K leads to the structure destruction. Internal mechanical compressive stresses at the "СdxPb1-xS film-substrate" interface was calculated in the range of 300–900 K for the first time ever, the highest values reached 2000–2750 kN/m2 for a number of the films compositions. In contrast to solid solutions, the expansion stresses up to 100 kN/m2 were derived for the CdS layer at 900 K. The obtained temperature steadiness boundaries and the mechanical stresses of СdxPb1-xS films must be taken into account in the development of photonic devices based on such materials

THE EFFECT OF COBALT DOPANT ON THE PHOTOELECTRIC PROPERTIES OF PbS THIN FILMS

PbS thin films doped with cobalt chloride were obtained by chemical deposition from aqueous media onto glass substrates. The effect of an alloying impurity on the photoelectric properties of PbS thin films is considered

Assessment of Mechanical Stresses That Occur on the interface “CDPBS Film – Substrate”

Химическим осаждением на подложках из ситалла, кремния (111), предметного стекла, стекло+ITO, плавленого кварца и пористого стекла синтезированы пленки CdPbS. Результаты расчетов величины механических напряжений на интерфейсе “пленка–подложка” показали, что пленки подвергаются механическим напряжениям сжатия.CdPbS films were synthesized by chemical deposition on substrates made of sitall, silicon (111), slide glass, glass+ITO, fused quartz, and porous glass. Results of calculations of mechanical stresses on the film-substrate interface” it was shown that the films are subjected to mechanical compression stresses

The Effect of Chromium Doping on the Morphology of PbS Films

Thin films of PbS doped with chromium with a thickness from 410 to 500 nm were ob-tained by chemical deposition from aqueous media on glass substrates. The effect of an al-loying additive on the surface morphology of PbS thin films is considered
