Abstract
Lead telluride nanostructures were obtained on silicon substrates by thermal evaporation in vacuum. Growth occurred at three different distances between the evaporation source and the substrate. The distances between the evaporator and the evaporation source were 5 cm; 7.5 cm and 10 cm. Structural characteristics were studied using XRD, SEM, EDX, AFM analyses. These methods provided information about the crystal structure, morphology, microstructure and elemental composition of the material. X-ray diffraction analysis showed that thin films of lead telluride obtained by thermal evaporation in vacuum have a cubic crystal structure. This experimental work was carried out to determine the effect of distance on the structure of lead telluride (PbTe). During the experiment, the optimal modes for the formation of lead telluride (PbTe) nanostructures were determined, which was equal to d = 10 cm. It was found that lead telluride (PbTe) nanostructures are formed at this distance.
期刊介绍:
Chalcogenide Letters (CHL) has the aim to publish rapidly papers in chalcogenide field of research and
appears with twelve issues per year. The journal is open to letters, short communications and breakings news
inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in
structure, properties and applications, as well as those covering special properties in nano-structured
chalcogenides are admitted.
