Спектр применения инфракрасных фотодетекторов с квантовыми ямами (QWIP) очень широк. Такие фотодетекторы являются достаточно востребованными на рынке, поэтому очень важно глубокое понимание принципа их работы.</p></sec><sec><title>Цель работы</title><p>Цель работы. Исследование влияния потенциального барьера AlGaAs, окружающего квантовые ямы GaAs, на значение рабочего напряжения смещения QWIP длинноволновой области спектра (8…10 мкм).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для проведения эксперимента были изготовлены образцы QWIP на основе системы полупроводниковых материалов GaAs/AlGaAs методом молекулярно-пучковой эпитаксии. Фоточувствительная (активная) область структур содержала 50 квантовых ям GaAs толщиной 50 Å, разделенных барьерами AlGaAs. Квантовые ямы легировались in situ донорной примесью – кремнием. Длина волны максимума спектральной чувствительности всех образцов находилась в диапазоне 8…9 мкм. Варьируемым параметром являлась ширина барьера. После прохождения технологического маршрута планарной модификации на всех структурах были сняты вольт-амперные характеристики.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено, что уменьшение толщины барьера способно сместить пик фоточувствительности в область меньших напряжений смещения при незначительном увеличении силы темнового тока.</p></sec><sec><title>Заключение</title><p>Заключение. Исследование влияния значения приложенного напряжения смещения представляет интерес не только с научной точки зрения – результаты помогут лучше понять поведение темнового тока в QWIP, а также позволят управлять максимумом токовой чувствительности, смещая ее в область требуемых рабочих напряжений мультиплексоров.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Quantum well infrared photodetectors (QWIP) are characterized by a wide application range. A large market demand for such photodetectors determines the importance of elucidating the principle of their operation.</p></sec><sec><title>Aim</title><p>Aim. To carry out a research study into the influence of the AlGaAs potential barrier surrounding GaAs quantum wells on the QWIP operating bias voltage in the long-wavelength region of the spectrum (8…10 μm).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. QWIP experimental samples were manufactured based on the GaAs/AlGaAs semiconductor material system using molecular beam epitaxy. The photosensitive (active) region of the structures contained 50 GaAs quantum wells with a thickness of 50 Å thick separated by AlGaAs barriers. Quantum wells were doped in situ with silicon as a donor impurity. The wavelength of the maximum spectral sensitivity of all samples ranged within 8…9 μm. The barrier width was the variable parameter. After passing the planar modification process route, the current–voltage characteristics were measured in all structures.</p></sec><sec><title>Results</title><p>Results. Reduction in the barrier thickness is capable of shifting the peak of photosensitivity towards the region of lower bias voltages with a slight increase in the dark current values.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study of the influence of the applied bias voltage presents both scientific and practical interest. On the one hand, the results improve the current understanding of the behavior of the dark current in QWIP. On the other, they provide the possibility of managing the maximum current sensitivity, shifting it towards the region of the required operating voltages of the multiplexers.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инфракрасные фотодетекторы с квантовыми ямами</kwd><kwd>темновой ток</kwd><kwd>фоточувствительность</kwd><kwd>вольт-амперные характеристики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>quantum well infrared photodetectors</kwd><kwd>dark current</kwd><kwd>spectral photosensitivity</kwd><kwd>current–voltage characteristics</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">Quantum well infrared photodetector research and development at Jet Propulsion Laboratory / S.
