Рассчитан спектр коэффициента усиления прибора, полученный в результате численного моделирования в рамках диффузионно-дрейфовой модели и модели захвата-рассасывания носителей с игнорированием вклада радиационной эмиссии. Показано, что диапазон поглощения фотодетектора при нулевом смещении находится в пределах от 4 до 6 мкм, при этом пик поглощения наблюдается при 4,64 мкм. Произведен расчет зависимости доступного фототока от длины волны и угла падения неполяризованного монохроматического светового луча. Выполнена оценка темного тока при различных температурах.</p></abstract><trans-abstract xml:lang="en"><p>A simulation procedure for analyzing the electrical and optical characteristics of an AlGaN/GaN intersubbandquantum well middle-wavelength infrared photodetector is presented. The photoconductive gain spectrumwas simulated by coupling the drift-diffusion and capture-escape models in the active region of the devicestructure and by ignoring the contribution of radiative emission. It was shown that the photodetector at zero biasis sensitive over a spectral range from 4 to 6 μm, with the peak absorption occurring at 4.64 μm. The dependenceof the available photocurrent on both the wavelength and the angle of incidence of an unpolarized monochromaticbeam of light was also evaluated. An assessment of the dark current characteristics was estimated at varioustemperatures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инфракрасное излучение</kwd><kwd>квантовая яма</kwd><kwd>межподзонный переход</kwd><kwd>моделирование</kwd><kwd>модель захвата-рассасывания</kwd><kwd>нитрид галлия</kwd><kwd>оптическое усиление</kwd><kwd>оптоэлектроника</kwd><kwd>поглощение</kwd><kwd>фотодетектор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>infrared radiation</kwd><kwd>quantum well</kwd><kwd>intersubband transition</kwd><kwd>simulation</kwd><kwd>capture-escape model</kwd><kwd>gallium nitride</kwd><kwd>optical gain</kwd><kwd>optoelectronics</kwd><kwd>absorption</kwd><kwd>photodetector</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнялась в рамках задания 1.4.4 Государственной программы научных исследований «Цифровые и космические технологии, безопасность человека, общества и государства».</funding-statement><funding-statement xml:lang="en">This work is supported by the grant 1.4.4 of Belarusian National Scientific Research Program “Digital and Space Technologies, Human and Public Safety and National Security”.</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">Li H., Yang Z.
