Получены величины изменения поляризации и энергетический барьер соответствующего перехода. Проведено исследование устойчивости данного перехода. Представлены результаты серии вычислительных экспериментов с применением высокопроизводительных вычислительных систем гибридной архитектуры на базе Центра коллективного пользования Федеральный исследовательский центр «Информатика и управление». Анализ результатов показывает, что, несмотря на невысокий энергетический барьер перехода, вероятность самопроизвольной смены поляризации невелика благодаря невозможности смены поляризации отдельной ячейки без учета влияния поляризаций соседних ячеек. </p></abstract><trans-abstract xml:lang="en"><p>The work is devoted to the study of the process of changing the polarization of hafnium oxide crystals in the orthorhombic phase associated with the gradual weakening of the polarization effects in FeRAM elements based on thin films of hafnium oxide HfO2. To solve the problem, quantum-mechanical calculations of the structure of orthorhombic hafnium oxide were carried out, a possible way of crystal rearrangement during a change in polarization upon application of voltage was identified, and its optimization was carried out using the elastic band method. The values of the polarization change and the energy barrier of the corresponding transition are obtained. A study of the stability of this transition has been carried out. The results of a series of computational experiments using high-performance computing systems of hybrid architecture based on the Center for Collective Use of the FRC IU RAS are presented. An analysis of the results shows that, despite the low energy barrier of the transition, the probability of a spontaneous change in polarization is low due to the impossibility of changing the polarization of an individual cell without taking into account the influence of the polarizations of neighboring cells.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оксид гафния</kwd><kwd>поляризация</kwd><kwd>энергетический барьер</kwd><kwd>квантово-механические расчеты</kwd><kwd>высокопроизводительные вычислительные системы</kwd><kwd>метод эластичной ленты</kwd><kwd>оптимизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hafnium oxide</kwd><kwd>polarization</kwd><kwd>energy barrier</kwd><kwd>quantum mechanical calculations</kwd><kwd>high-performance computing systems</kwd><kwd>elastic band method</kwd><kwd>optimization</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнялась с использованием инфраструктуры Центра коллективного пользования «Высокопроизводительные вычисления и большие данные» (ЦКП «Информатика») ФИЦ ИУ РАН (г.
