description: The main objective of this work was the growth of the Pb1-ySnyTe /BaF2/Ca1-xBaxF2/CaF2/Si(111) nanoheterostructures using molecular beam epitaxy method. The choice of these particular substances is due to the fact that Pb1-ySnyTe (further PST) with theÂ  y valueÂ  exceeding 0.4-0.3 exhibits the properties of a topological insulator. The possibility of using this material in various fields, such as spintronics, quantum computing, quantum information science etc., allows one to create a promising research object. The potential application of topological insulators can lead to the creation of new technologies and devices with improved characteristics and functionality. An important step in the growth of a topological insulator is the choice of substrate and the creation of a buffer layer. The growth of calcium fluoride on silicon has been studied more than three decades, however, for a smoother transition along the lattice constant from PST to silicon, it was decided to introduce, besides barium fluoride, a solid solution of calcium-barium fluoride. The obtained samples were analyzed by atomic force microscopy and X-ray diffraction method with reciprocal space mapping (XRD-RSM). The result of the work is grown nanoheterostructures, comparative analysis of their surface morphology and quantification of the mutual influence of layers. The use of a calcium-barium fluoride solid solution improved the PST growth technology, which results in a good planarity and interface quality of the grown samples. Thus, further research in this area could be important for the area of micro- and nanoelectronics, and physics of topological insulators.
