Исследованы особенности получения пленок Ga1–xInxAs методом зонной перекристаллизации градиентом температур. Смысл метода заключается в последовательной перекристаллизации частей расплава источника, движущегося под действием температурного градиента. Метод. В поле температурного градиента 30 К/см через тонкую газовую зону в специально разработанной графитовой кассете получены пленки Ga1–xInxAs на подложках GaAs при температуре 1123 К. В качестве газа носителя использована смесь азота и водорода в соотношении 1:1. Толщина газовой зоны между источником и подложкой составила 1 мм, время осаждения для всех пленок — 10 мин. Основные результаты. Исследована кинетика роста, морфология и структура химических связей полученных пленок. По результатам теоретического расчета установлено, что увеличение концентрации индия приводит к понижению скорости роста пленок до 0,3137 мкм/мин. Выполнено сравнение теоретического расчета и экспериментальных данных, которое показало расхождение значений скорости роста для пленок с концентрацией индия в ростовом источнике более 20 %, что связано с сегрегацией индия на поверхность пленки. Среднеквадратическая шероховатость пленок составила от от 9,1 до 24,2 нм. Подтверждено, что содержание индия в ростовом источнике существенно влияет на свойства выращенных пленок и приводит к уменьшению скорости роста, увеличению упругих напряжений в слое и нестехиометрическому составу пленки. Установлено, что с увеличением концентрации индия в пленке наблюдается существенное смещение частоты LO- и TO-фононных мод GaAs влево на 13 и 16 см–1 соответственно из-за влияния упругих механических напряжений. Обсуждение. Представленные результаты продемонстрировали, что методом зонной перекристаллизации в градиенте температур получены пленки твердого раствора Ga1–xInxAs, которые имеют ближний порядок химических связей.</p></abstract><trans-abstract xml:lang="en"><p>Solid solution Ga1–xInxAs is widely used in modern optoelectronics as a material for p-i-n photodetectors, lasers emitting in the spectral range 1.3–1.55 μm. In this paper, the features of obtaining Ga1–xInxAs flms by the method of zone recrystallization with a temperature gradient, the essence of which is the sequential recrystallization of parts of the source melt moving under the action of a temperature gradient, are studied. Ga1–xInxAs flms on GaAs substrates were obtained in a temperature gradient feld through a thin gas zone in a specially designed graphite cassette. The flms were prepared at a temperature of 1123 K with a temperature gradient of 30 K/cm. A 1:1 mixture of nitrogen and hydrogen was used as the carrier gas. The thickness of the gas zone between the source and the substrate was 1 mm. The deposition time for all flms was 10 min. The growth kinetics, morphology, and structure of the chemical bonds of the obtained flms have been studied. Based on the results of theoretical calculations, it was found that an increase in the concentration of indium leads to a decrease in the flm growth rate to 0.3137 µm/min. A comparison of the results of theoretical calculations with experimental results showed a discrepancy between the growth rates for flms with an indium concentration in the growth source of more than 20 %, which is primarily due to the segregation of indium on the flm surface. The flms have an RMS roughness from 9.1 to 24.2 nm. It is shown that the content of indium in the growth source signifcantly affects the properties of the grown flms and leads to a decrease in the growth rate, an increase in the elastic stresses in the layer, and a nonstoichiometric composition of the flm. It has been established that with an increase in the indium concentration in the flm, a signifcant shift in the frequency of the LO and TO phonon modes of GaAs to the left by 13 and 16 cm–1, respectively, is observed due to the infuence of elastic mechanical stresses. The presented results show that Ga1–xInxAs solid solution flms with short-range order of chemical bonds were obtained by the method of zone recrystallization in a temperature gradient..</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поле температурного градиента</kwd><kwd>тонкая газовая зона</kwd><kwd>соединения III–V</kwd><kwd>Ga1–xInxAs</kwd><kwd>рамановская спектроскопия</kwd><kwd>атомно-силовая микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>temperature gradient feld</kwd><kwd>thin gas band</kwd><kwd>III–V compounds</kwd><kwd>Ga1–xInxAs</kwd><kwd>Raman spectroscopy</kwd><kwd>atomic force microscopy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ФИЦ ЮНЦ РАН № 122020100254-3 (исследования  морфологии поверхности пленок) и № 122020100326-7 (рамановские исследования и определение химического  состава), а также с использованием ресурсов центра коллективного пользования Северо-Кавказского  федерального университета и при финансовой поддержке Минобрнауки России, уникальный идентификатор проекта RF-2296.61321X0029 (соглашение № 075-15-2021-687) (получение экспериментальных образцов пленок).
