An unusual effect of light on the nature of resistive switching (RS) was discovered: in the high-resistance state the memristor conductivity increases under illumination, whereas in the low-resistance state negative photoconductivity (i.e., a noticeable decrease) is observed during cyclic RS. A qualitative model, that describes the switching mechanism under optical excitation and in its absence, is proposed. The characteristics of RS and the possibility of controlling them using illumination demonstrate the possibility of using hybrid PPX-memristors as sensory and synaptic elements in the development of neuromorphic computer vision systems.</p></abstract><trans-abstract xml:lang="ru"><p>Исследованы структурные и мемристичные свойства слоистых образцов Cu/ППК–PbTe/ITO на основе парилена (поли-n-ксилилен, ППК) с наночастицами PbTe. Обнаружено необычное влияние света на характер резистивного переключения (РП) — в высокоомном состоянии проводимость мемристора растет при подсветке, тогда как, в низкоомном состоянии наблюдается отрицательная фотопроводимость (т.е. заметное ее уменьшение) при циклических РП. Предложена качественная модель, описывающая механизм переключения при оптическом возбуждении и в его отсутствии. Характеристики РП и возможность управления ими с помощью освещения демонстрируют возможность использования гибридных ППК-мемристоров в качестве сенсорных и синаптических элементов при разработке нейроморфных систем компьютерного зрения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>resistive switching</kwd><kwd>optoelectronic memristor</kwd><kwd>parylene</kwd><kwd>nanocomposite</kwd><kwd>PbTe</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>резистивное переключение</kwd><kwd>оптоэлектронный мемристор</kwd><kwd>парилен</kwd><kwd>нанокомпозит</kwd><kwd>PbTe</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда (проект № 24-19-00200) в части исследований влияния освещения на мемристичные свойства образцов Cu/ППК–PbTe/ITO и государственного задания НИЦ «Курчатовский институт» в части синтеза образцов и изучения их структурных особенностей.
