С помощью измерения вольт-амперных характеристик оценена электропроводность мемристора в низко- и высокоомном режимах работы. Для определения энергии активации использованы закон Аррениуса и положения термодинамики необратимых процессов, в частности второй постулат Онзагера, согласно которому скорость роста необратимой части энтропии стремящейся к равновесию системы пропорциональна сумме произведений протекающих в системе потоков на соответствующую каждому потоку обобщенную термодинамическую силу. За равновесное состояние мемристора принимали состояние, в котором мемристор терял способность функционировать как ячейка резистивной памяти. В качестве потока вещества использовали поток ионов Ag+ — электромиграцию. Для первого процесса энергия активации составляла 0,24 эВ, а для второго — 1,16 эВ. Разные значения энергии активации отражают различие между агломерационным механизмом формирования токопроводящего канала, типичным для мемристора Ag/SnSe/Ge2Se3/W, и «стандартным» механизмом переноса вещества на основе группы точечных дефектов, сопровождающим процесс деградации мемристора.</p></abstract><trans-abstract xml:lang="en"><p>In an Ag/SnSe/Ge2Se3/W ionic type memristor, the activation energy of two main processes responsible for its operation has been determined, namely: the activation energy for the formation of a conductive channel and the activation energy for memristor degradation. By measuring the current-voltage characteristics, the electrical conductivity of the memristor in low- and high-resistance operating modes was assessed. To determine the activation energy, the Arrhenius law and the provisions of the thermodynamics of irreversible processes were used, in particular the second postulate of Onsager, according to which the growth rate of the irreversible part of the entropy of a system tending to equilibrium is proportional to the sum of the products of the flows occurring in the system and the generalized thermodynamic force corresponding to each flow. The equilibrium state of the memristor was taken to be the state in which the memristor lost the ability to function as a resistive memory cell. The flow of Ag+ ions – electromigration was used as a substance flow. For the first process, the activation energy was 0.24 eV, and for the second, 1.16 eV. The different values of activation energy reflect the difference between the agglomeration mechanism of formation of a current-conducting channel, typical of an Ag/SnSe/Ge2Se3/W memristor, and the “standard” mechanism of substance transfer based on a group of point defects, which accompanies the process of memristor degradation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электропроводность</kwd><kwd>твердый электролит</kwd><kwd>аморфная матрица</kwd><kwd>энергия активации</kwd><kwd>агломерационный механизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrical conductivity</kwd><kwd>solid electrolyte</kwd><kwd>amorphous matrix</kwd><kwd>activation energy</kwd><kwd>agglomeration mechanism</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">This work was supported by the Russian Foundation for Basic Research, project 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">Kim K.М., Jeong D.S., Hwang C.S.
