Показано наличие пика основных переходов в квантовых точках при 1,2 эВ (данные моделирования) и 1,12 эВ (экспериментальные данные). Экспериментальный пик имеет большую ширину (0,13 эВ) на половине максимума излучения основных переходов в квантовых точках, по сравнению с моделируемым (0,06 эВ). Наблюдается смещение экспериментального пика в длинноволновую область приблизительно на 65 мэВ, что говорит о наличии в структуре дисперсии по размерам квантовых точек. Моделируемая темновая вольтамперная характеристика при температуре 90 К и нулевом смещении показывает значение плотности темнового тока 10-7 А/см2, что на порядок меньше результатов измерения (10-6 А/см2). Наблюдается различие в характере распре деления зависимости при отрицательном и положительном смещении между экспериментом и резуль татами моделирования, связанное с присутствием квантовых точек большего размера.</p></abstract><trans-abstract xml:lang="en"><p>The simulation of the photoluminescence and dark current-voltage characteristics of heterostructures with a single layer of quantum dots. The presence of the peak quantum transitions in the main points at 1,2 eV (modeling) and 1,12 eV (experimental). The experimental peak has a greater width (0,13 eV) at half maximum fundamental radiation transitions in quantum dots, compared to the modeled (0,06 eV). There is a shift of the experimental peak to longer wavelengths by about 65 meV, indicating that the presence in the dispersion structure the size of quantum dots. The dark current-voltage simulated characteristic at a temperature of 90 K and zero bias shows the value of the dark current density of 10-7 A/cm2, which is much smaller than the measurement results (10-6 A/cm2). There is a difference in the nature of the distribution depending on when the negative and positive displacement between experiment and simulation results associated with the presence of quantum dots larger.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>квантовая точка</kwd><kwd>моделирование</kwd><kwd>вольтамперная характеристика</kwd><kwd>фотолюминесценция</kwd><kwd>фотодетектор</kwd><kwd>ближний ИК диапазон</kwd><kwd>quantum dot</kwd><kwd>current-voltage characteristic</kwd><kwd>photoluminescence</kwd><kwd>photodetector</kwd><kwd>near-infrared</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">Wei-Hsun Lin, Kuang-Ping Chao, Chi-Che Tseng, Shu-Cheng Mai, Shih-Yen Lin, Meng-Chyi Wu.
