Two-dimensional graphene-like materials have unusual electrical and optical properties that make them promising for use in nano- and microelectronics. One of the types of two-dimensional materials is the class of transition metal dichalcogenides (TMDC). Chemical formula is MX2, where M is the transition metal (Mo, W, Ti, Pt, Pd), and X is the chalcogen (S, Se). These compounds possess semiconductor properties with a small number of atomic layers, which makes it important to study the properties of such thin structures.  To date, there are a number of studies showing the possibility of using multilayer structures of transition metal dichalcogenides as vertical tunnel transistors [1]. This possibility is due to the high rate of charge transfer from the monolayer of one TMDC to the monolayer of the other. This ultrafast transition of charge carriers is accompanied by the appearance of interlayer excitons whose lifetime exceeds the lifetime of such in separate monolayers of DPM. For interlayer excitons, the lifetime is about 1.8 ns [2], while for interlayer excitons it is up to 10 ps, which can be useful for creating lasers, light-emitting diodes and photovoltaic devices.  Also, one of the promising types of materials are multilayer structures, consisting of layers of different TMDCs [3]. Samples of the multilayer structure of TMDC were firstly obtained in 2016. At the same time, experimental data were obtained for the first time on the spectral characteristics of this class of substances. The results of photoluminescence spectroscopy showed the presence of a new type of exciton-the interlayer exciton. Due to the novelty of multilayer structures based on different TMDCs, today there are no models describing the physical phenomena occurring in these materials, which make the solution of this problem very urgent [4].  The aim of the work is to study the properties of excitons in multilayer structures for various combinations of transition metal dichalcogenides. The expected results are a significant contribution to the study of the features of band structures of multilayer materials and on them of interlayer excitons.
