Изучены вольт-амперные характеристики в условиях освещения ксеноновой лампой с выделением монохроматической линии в диапазоне 400–800 нм и в темновом режиме. Синтезированные структуры показали наличие фототока на обратной ветви вольт-амперных характеристик во всем исследованном диапазоне длин волн освещения. Максимальный ток обратной ветви для структуры с нелегированным титанатом бария был достигнут при воздействии излучения с длиной волны 470 нм и составил около 0,6 мкА для диапазона напряжения смещения от 2 до 10 В. Легирование титаната бария европием приводит к увеличению фототока на 17–26 %.</p></abstract><trans-abstract xml:lang="en"><p>Photosensitive silicon/barium titanate/nickel structures with undoped barium titanate and doped europium were synthesized using the sol-gel method. The current-voltage characteristics were studied under illumination with a xenon lamp, highlighting a monochromatic line in the range of 400–800 nm and in dark mode. The synthesized structures showed the presence of a photocurrent on the reverse branch of the current-voltage characteristics over the entire studied range of illumination wavelengths. The maximum reverse branch current for a structure with undoped barium titanate was achieved when exposed to radiation with a wavelength of 470 nm and was about 0.6 μA for a bias voltage ranging from 2 to 10 V. Doping barium titanate with europium leads to an increase in the photocurrent by 17–26 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>титанат бария</kwd><kwd>вольт-амперные характеристики</kwd><kwd>фототок</kwd><kwd>золь-гель-синтез</kwd><kwd>европий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>barium titanate</kwd><kwd>current-voltage characteristics</kwd><kwd>photocurrent</kwd><kwd>sol-gel synthesis</kwd><kwd>europium</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ржанов, А.
