Показано, что наибольшая электронная плотность как всех валентных, так и d-состояний локализована у поверхностей нанокластеров с наибольшей кривизной. Минимумы полной и d-электронной плотности локализованы преимущественно на атомах приповерхностного слоя поверхностей с наименьшей кривизной. Энергия связи, приходящаяся на атом, растет с ростом размеров НК, для отдельных НК она чуть выше, чем для системы из двух контактирующих НК. Плотность же электронных состояний системы контактирующих НК 2 нм не зависит от типа их контакта.</p></abstract><trans-abstract xml:lang="en"><p>In this work, titanium nanoclusters with sizes of 2 and 4 nm are studied by semi-empirical calculation methods. For the detached and contacting nanoclusters the optimal geometry, energy and orbitals are obtained, structural, electronic, and charge properties are studied. It is shown that the highest electron density for both all valence and d-valence states is localized near the surface of nanoclusters with the highest curvature. The minimal local density of those states is localized on atoms near the surfaces of nanoclusters with the highest curvature. With an increase in the size of the cluster, the binding energy per atom increases. For detached cluster it is slightly higher than for a system of contacting ones. The density of electronic states of the system of 2 nm nanoclusters in contact does not depend on the type of their contact, and there are more regular zones in the 4 eV-surrounding of Fermi energy, then in the detached 2 nm nanoclusters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нанокластеры</kwd><kwd>переходные металлы</kwd><kwd>титан</kwd><kwd>термо-фотовольтаика</kwd><kwd>метод сильной связи</kwd><kwd>электронная структура</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanoclusters</kwd><kwd>transition metals</kwd><kwd>titanium</kwd><kwd>thermo-photovoltaics</kwd><kwd>TPV</kwd><kwd>tight-binding</kwd><kwd>electronic structure</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа была поддержана грантом Российского научного фонда (проект № 21-72-10054)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">&lt;em&gt;Bricchi B.R. et al.&lt;/em&gt; // ACS App. Mater.
