Как MoTe2, так и MoS2 в объемном состоянии являются непрямозонными полупроводниками, в то время как их монослои, а также соединения MoS2-x Tex при x &lt; 0,5 либо x &gt; 1,5 становятся прямозонными. В случае, когда концентрация атомов теллура меньше концентрации атомов серы, ширина запрещенной зоны тройного соединения линейно уменьшается с повышением концентрации атомов теллура.</p></abstract><trans-abstract xml:lang="en"><p>The electron energy band gap in one monomolecular layer of molybdenum dichalcogenide MoS2 is reduced upon substitution of S atoms by Te ones from 1,84 to 1,17 eV in the case of MoTe2. Both MoTe2 and MoS2 compounds in a bulk phase are indirect-gap semiconductors while one monomolecular layer of MoS2- x Tex compounds are transforming into direct-gap compounds for x &lt; 0,5 or x &gt; 1,5. The band gap dependence has a linear behavior in the case when the concentration of Te atoms is smaller than the concentration of S atoms.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дисульфид молибдена</kwd><kwd>мономолекулярный слой</kwd><kwd>электронная структура</kwd><kwd>запрещенная зона</kwd></kwd-group><kwd-group xml:lang="en"><kwd>molybdenum disulfide</kwd><kwd>monolayer</kwd><kwd>electronic structure</kwd><kwd>band gap</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">Geim A.K., Novoselov K.S. // Nature Materials. 2007.
