За токопроводящий канал принималась обогащенная ионами Hf фаза HfOx (x &lt; 2), имеющая структуру фазы Магнели, и, соответственно, обладающая повышенной электропроводностью. Разработан механизм образования, роста и растворения фазы HfOx в условиях биполярного режима работы мемристора, который позволяет управлять потоками кислородных вакансий. Токопроводящий канал имел форму цилиндра с радиусом, варьируемым в пределах 5—10 нм. Показано, что с увеличением толщины канала увеличивается и площадь гистерезисных петель вольт-амперной характеристики, что связано с возрастающей энергетической нагрузкой при работе мемристора. Разработана модель, которая позволяет проводить количественные расчеты и, следовательно,  может быть использована при конструировании биполярных мемристоров для оценки тепловых потерь во время их работы. </p></abstract><trans-abstract xml:lang="en"><p>The operation of the TiN/HfO2/Pt bipolar memristor has been simulated by the finite elements method using the Maxwell steady state equations as a mathematical basis. The simulation provided knowledge of the effect of conductive filament thickness on the shape of the I-V curve. The conductive filament has been considered as the highly conductive Hf ion enriched HfOx phase (x &lt; 2) whose structure is similar to a Magneli phase. In this work a mechanism has been developed describing the formation, growth and dissolution of the HfOx phase in bipolar mode of memristor operation which provides for oxygen vacancy flux control. The conductive filament has a cylindrical shape with the radius varying within 5–10 nm. An increase in the thickness of the conductive filament leads to an increase in the area of the hysteresis loop of the I-V curve due to an increase in the energy output during memristor operation. A model has been developed which allows quantitative calculations and hence can be used for the design of bipolar memristors and assessment of memristor heat loss during operation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>уравнения Максвелла</kwd><kwd>метод конечных элементов</kwd><kwd>биполярный режим</kwd><kwd>проводящая фаза</kwd><kwd>тепловые потери</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Maxwell equations</kwd><kwd>finite elements method</kwd><kwd>bipolar mode</kwd><kwd>conductive phase</kwd><kwd>heat loss</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского фонда фундаментальных исследований, грант № 19-29-03003 МК.</funding-statement><funding-statement xml:lang="en">The work was carried out with financial support from the Russian Basic Research Fund, Grant No. 19-29-03003 MK.</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">Bersuker G., Gilmer D.C., Veksler D., Kirsch P., Vandelli L., Padovani A., Larcher L., McKenna K., Shluger A., Iglesias V., Porti M., Nafría M.
