Рассматриваются как Ni в междоузельной позиции, так и в позиции замещения Hf. Показано, что Ni облегчает образование кислородных вакансий и их кластеризацию. Локализация носителей заряда происходит преимущественно на кислородных вакансиях, тогда как никель оказывает косвенное влияние на транспорт заряда. Комплексы никеля и вакансий кислорода не формируют мелких ловушек. Показано, что филаментарные структуры в виде непрерывных металлических цепочек в HfO<sub>2</sub> не обладают металлической проводимостью.</p></trans-abstract><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда, грант №24-19-00650.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>M.
