Нанокластеры получены методом кластерного осаждения из газовой фазы с помощью магнетронного распыления мишени тантала. Формирование кластеров производилось с использованием кластерного источника Nanogen-50 (Mantis Deposition) с квадрупольным масс-фильтром, интегрированным в камеру препарирования сверхвысоковакуумной системы Omicron Multiprobe MXPS VT AFM-25. Установлено, что для сферических нанокластеров разных размеров туннельный ток существенно различается, измеренная дифференциальная вольтамперная характеристика нанокластеров вблизи энергии Ферми носит немонотонный характер, что может свидетельствовать об изменении плотности электронных состояний вблизи энергии Ферми. Это изменение туннельной проводимости нанокластеров в зависимости от их размера свидетельствует о наличии перехода металл-неметалл в нанокластерах металлов на поверхности полупроводников при уменьшении размера кластеров.</p></abstract><trans-abstract xml:lang="en"><p>The results of studying the electronic states of tantalum nanoclusters on a silicon substrate by scanning tunneling spectroscopy are presented. Nanoclusters were obtained by the method of cluster deposition from the gas phase using magnetron sputtering of a tantalum target. Clusters were formed using a Nanogen-50 cluster source (Mantis Deposition) with a quadrupole mass filter integrated into the preparation chamber of the Omicron Multiprobe MXPS VT AFM-25 ultrahigh vacuum system. It has been established that for spherical nanoclusters of different sizes, the tunneling current differs significantly, the measured differential current-voltage characteristic of nanoclusters near the Fermi energy is nonmonotonic, which may indicate a change in the density of states near the Fermi energy. This change in the tunneling conductivity of nanoclusters depending on their size indicates the presence of a metal-nonmetal transition in metal nanoclusters on the semiconductor surface as the cluster size decreases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наночастицы</kwd><kwd>нанокластерые</kwd><kwd>тонкие пленки</kwd><kwd>оксид тантала</kwd><kwd>Ta2O5</kwd><kwd>СТМ</kwd><kwd>СТС</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanoparticles</kwd><kwd>nanoclusters</kwd><kwd>thin films</kwd><kwd>tantalum oxide</kwd><kwd>Ta2O5</kwd><kwd>STM</kwd><kwd>STS</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда (проект № 21-72- 10054).</funding-statement><funding-statement xml:lang="en">The research was supported by a grant from the Russian Science Foundation (project No. 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">Hutter E., Fendler J.H. // Adv.
