Установлено, что объемный Ca2Si и тонкие пленки Ca2Si(010) и (100) являются прямозонными полупроводниками, а поверхностные состояния приводят к металлическим свойствам тонких пленок Ca2Si(001).</p></abstract><trans-abstract xml:lang="en"><p>The results of theoretical research of band structures of Ca2Si bulk and Ca2Si thin films with surfaces (001), (010), (100) are presented. It`s found that Ca2Si bulk and thin film Ca2Si(010) and (100) are direct bandgap semiconductors while Ca2Si(001) thin films show the metallic properties because of surface`s states.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тонкие пленки</kwd><kwd>силицид кальция</kwd><kwd>зонная структура</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">Maex K., Van Rossum M. // Properties of metal silicides. 1995.
