Двумерные полупроводниковые гетероструктуры являются предметом изучения фундаментальной науки и представляют интерес для различных приложений в наноэлектронике. Известно, что можно создавать как вертикальные, так и планарные гетероструктуры. В вертикальных гетероструктурах монослои уложены друг над другом и связаны друг с другом слабыми связями, называемыми вандерваальсовскими. В планарных гетероструктурах материалы совмещены вдоль слоев и атомы взаимодействуют между собой сильными ковалентными связями. Планарные гетероструктуры, в частности гетероструктура MoS2/WS2, обладают более тонкой перестройкой зонной структуры, которая проявляется в наблюдаемых оптических свойствах материала. Благодаря этому материал может использоваться в электронике для создания устройств на основе дихалькогенидов переходных металлов. Более того, планарная гетероструктура имеет различные оптические свойства в зависимости от поляризации света и направления распространения световых волн. Такое поведение позволяет использовать этот материал для создания оптических и связанных с ними устройств, таких как фильтры, оптические волокна и датчики. В настоящей работе мы исследуем электронные и оптические свойства планарной гетероструктуры MoS2/WS2 на основе теории функционала плотности. Рассчитана зонная структура планарной гетероструктуры MoS2/WS2, вычислены комплексные диэлектрические проницаемости и комплексные показатели преломления монослоев MoS2, WS2 и гетероструктуры MoS2/WS2.</p></abstract><trans-abstract xml:lang="en"><p>Semiconductor heterostructures are widely used in various electronic devices. Two-dimensional semiconductor heterostructures are the subject of study in fundamental science and are of interest for various applications in nanoelectronics. It is known that both vertical and planar heterostructures can be created. In vertical heterostructures, monolayers are stacked on top of each other and are connected to each other by weak bonds, called van der Waals bonds. In planar heterostructures, the materials are aligned along the layers and the atoms interact with each other by strong covalent bonds. Planar heterostructures, in particular, the MoS2/WS2 heterostructure, have a finer band structure rearrangement, which manifests itself in the observed optical properties of the material. Due to this,the material can be used in the electronics to create devices based on transition metals – typical semiconductors of such materials. Moreover, a planar heterostructure has different optical properties depending on the polarization of light and the direction of propagation of light waves. This behavior allows this material to be used to create optical and related devices such as filters, optical fibers, and sensors. In this paper we study the electronic and optical properties of the planar MoS2/WS2 heterostructure based on the density functional theory. The band structure of the planar MoS2/WS2 heterostructure is calculated, and the complex permittivities and complex refractive indices of the MoS2 and WS2 monolayers and the MoS2/WS2 heterostructure are calculated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>теория функционала плотности</kwd><kwd>кристаллическая структура</kwd><kwd>двумерные  материалы</kwd><kwd>планарная гетероструктура MoS2 /WS2</kwd><kwd>оптические свойства</kwd><kwd>диэлектрическая  проницаемость</kwd><kwd>показатель преломления</kwd><kwd>коэффициент затухания</kwd><kwd>зонная структура</kwd></kwd-group><kwd-group xml:lang="en"><kwd>density functional theory</kwd><kwd>crystal structure</kwd><kwd>two-dimensional materials</kwd><kwd>MoS2 /WS2  planar  heterostructure</kwd><kwd>optical properties</kwd><kwd>permittivity</kwd><kwd>refractive index</kwd><kwd>damping factor</kwd><kwd>band structure</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Grigorieva I.
