Он обладает множеством выдающихся характеристик, особенно сегнетоэлектрическими и диэлектрическими свойствами, которые могут быть улучшены путем легирования, что делает этот материал подходящим для широкого спектра применений. В настоящей работе исследовано влияние допирования Rh на структурные, оптические свойства и плотность электронных состояний данного соединения. Согласно нашим расчетам, допирование Rh представляет собой метод, который способствует повышению способности BaTiO3 к поглощению большего количества света и снижению избыточного потенциала, необходимого для окисления воды. Были проведены расчеты плотности электронных состояний с применением гибридного функционала HSE06. Анализ оптических свойств был выполнен на основе матричных элементов с переходным дипольным моментом. Исследования подтвердили, что поверхность (001) BaTiO3 с терминированным TiO2 обладает значительным потенциалом для применения в качестве катализатора. Допирование Rh приводит к расширению спектра поглощаемого света на весь видимый диапазон.</p></abstract><trans-abstract xml:lang="en"><p>Barium titanate is one of the most studied perovskite materials due to its substitution ability at both nodes of the crystal lattice, high dielectric constant, and stability. It has many outstanding characteristics, especially ferroelectric and dielectric properties, which can be improved by alloying, making this material suitable for a wide range of applications. In this paper, the effect of Rh doping on the structural, optical properties and electronic density of states of this compound is investigated. According to our calculations, Rh doping is a method that helps to increase the ability of BaTiO3 to absorb more light and reduce the excess potential required for water oxidation. Calculations of the electronic density of states were carried out using the hybrid functional HSE06. The analysis of optical properties was performed on the basis of matrix elements with a transient dipole moment. Studies have confirmed that the (001) BaTiO3 surface with terminated TiO2 has significant potential for use as a catalyst. Rh doping leads to an expansion of the spectrum of absorbed light over the entire visible range.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>теория функционала плотности</kwd><kwd>перовскит</kwd><kwd>ширина запрещенной зоны</kwd><kwd>фотокатализатор</kwd><kwd>электронная плотность состояний</kwd><kwd>поверхность</kwd><kwd>BaTiO3</kwd></kwd-group><kwd-group xml:lang="en"><kwd>density functional theory</kwd><kwd>perovskite</kwd><kwd>band gap</kwd><kwd>photocatalyst</kwd><kwd>electron density of states</kwd><kwd>surface</kwd><kwd>BaTiO3</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при финансовой поддержке Министерства науки и высшего образования Республики Казахстан, грант AP14869492 «Разработка нанокристаллических металлооксидных катализаторов для производства водорода».</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">Shi K., Zhang B., Liu K., Zhang J., Ma G.
