Коэффициент туннельной прозрачности для генерируемых солнечным светом электронов рассчитан с помощью разработанной модели на основе метода фазовых функций. В качестве инжектора спин-зависимых электронов в диоксид титана в структуре используется пленка ферромагнетика. Показано, что величина спиновой поляризации электронов на поверхностных состояниях составляет 10–25 %, что может способствовать реализации спинового катализа процессов разложения органических соединений на поверхности диоксида титана.</p></abstract><trans-abstract xml:lang="en"><p>Results of the simulation of spin-dependant tunneling of electrons to the surface states of the titanium dioxide, which are created by adsorbed organic impurities are performed. Tunneling transparency for sunlight generated electrons is calculated by the Phase function method. A ferromagnetic film is considered to be an injector of spin-dependent electrons to the titanium dioxide. It is shown that electron spin polarization at the surface states reaches 10–25 %. It can contribute to the spin enhanced catalysis peeling a surface from organic impurities.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spin-dependent tunneling</kwd><kwd>the tunneling transparency</kwd><kwd>titanium dioxide</kwd><kwd>surface states</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках проекта Государственной программы научных исследований «Конвергенция–2020».
