Изучены характеристики отжига и зависимость температуры детектирования от доз облучения. Результаты показывают, что в облученном электронами кристалле 4H-SiC доминирует эмиссия, связанная с дефектами углеродная антиструктура—вакансия (VCCSi)+. С повышением температуры детектирования излучение уменьшается и сдвигается в красную область, а полная ширина на полувысоте увеличивается, что связано с повышением концентрации носителей в результате термической активации при высокой температуре. Интенсивность излучения максимальна при Дозе облучения 7.9 × 1018 эл/см2, затем она уменьшается. Это свидетельствует о повреждении решетки, вызванном длительным высокоэнергетическим облучением, что уменьшает интенсивность радиационного дефекта в спектре.</p></abstract><trans-abstract xml:lang="en"><p>Low-temperature photoluminescence was employed to investigate the defects of 4H-SiC crystals after high-energy electron irradiation, and the annealing characteristics and dependence of the detecting temperature and irradiation doses were investigated. Results showed that the emission, associated with carbon antisite-vacancy (VCCSi)+ defects was dominant in the electron-irradiated 4H-SiC crystal. With increase in detecting temperature, the emission decreased demonstrating red-shifted, and the full width at halfmaximum broadened, which was attributed to the increase in the concentration of carriers arising from thermal activation at high temperature. The emission intensity was the highest value at an irradiation dose of 7.9×1018 e/cm2, and then began to decrease. This revealed the lattice damage caused by long-term high-energy irradiation, which reduced the intensity of the defect radiation in the spectrum.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>карбид кремния</kwd><kwd>фотолюминесценция</kwd><kwd>радиационный дефект</kwd><kwd>электронное облучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silicon carbide</kwd><kwd>photoluminescence</kwd><kwd>defect radiation</kwd><kwd>electron irradiation</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This study was funded by Fund Program for the Scientific Activities of Selected Returned Overseas Professionals in Shanxi Province (No. 20200024), Research Project Supported by Shanxi Scholarship Council of China (No. 2020-129), Shanxi Postgraduate Innovation Project (No. 2020SY413, 2020BY107), and the Key Research and Development Projects of Shanxi Province (No. 201803D121027).</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">Y.
