Обработки плазмой подвергалась поверхность AlGaN в рабочей камере установки плазмохимического осаждения перед запуском моносилана для формирования пленки SiОN. Изучено изменение транспортных свойств (проводимости и подвижности) слоя двумерного электронного газа и емкостных свойств структур. Экспериментально показано, что такая обработки приводит к изменению величины поляризационных зарядов как на границе «изолятор—AlGaN», так и на границе AlGaN/GaN. С помощью С—V-измерений в режиме гистерезиса установлено, что при управляющем напряжении (U &gt; +4÷+5 В) происходит захват части канальных электронов на глубоких центрах границы SiON/AlGaN, причем с увеличением продолжительности воздействия плазмой наблюдается резкий рост заряда, формируемого электронными граничными состояниями. Использование дополнительной обработки азотной плазмой переводит для нитридных структур работу из D-режима (Vth = –4 В) в Е-режим (Vth = +0,9 В).</p><p>С помощью Оже-измерений показано, что обработка плазмой приводит к изменению количества кислорода в слое SiON и в нанообластях барьерного слоя, причем с увеличением продолжительности воздействия плазмой наблюдается резкое уменьшение количества кислорода в этих слоях. Обнаружено также, что при обработке азотной плазмой происходит перераспределение Ga и Al на границе AlGaN/GaN т. е. в области слоя двумерного электронного газа. С помощью Оже-измерений вблизи границы SiON/AlGaN со стороны изолятора обнаружена локализация атомов азота, химически связанных с кремнием N(Si), с образованием на границе раздела пика, размер которого растет с увеличением продолжительности воздействия плазмой.</p></abstract><trans-abstract xml:lang="en"><p>The effect on the electrical parameters of the SiON/AlGaN/GaN structures of treatment of different durations of low-energy nitrogen plasma was studied. The AlGaN surface was subjected to plasma treatment in the working chamber of the plasma-chemical deposition unit before starting the monosilane to form the SiON film. Changes in the transport properties (conductivity and mobility) of the canal and capacitive properties of the structures were evaluated. It has been experimentally shown that such treatment leads to a change in the magnitude of polarization charges both at the insulator-AlGaN interface and at the AlGaN/GaN interface. With the help of C–V measurements-in the hysteresis mode, it is shown that at the control voltage U &gt; +4 — +5 V ), some of the channel electrons are captured at deep centers at the SiON-AlGaN interface, and with an increase in the duration of exposure to plasma time, a sharp increase is observed charge Qit, formed by electronic boundary states. The use of additional treatment with nitrogen plasma transfers work for nitride structures from the D-mode (Vth = –4 V) to the E-mode (Vth = +0.9 V).Using Auger-measurements, it was shown that plasma treatment leads to a change in the amount of oxygen in the SiON layer and in nano-regions of the barrier layer, and with an increase in the duration of plasma exposure, a sharp decrease in the amount of oxygen in these layers is observed. Also, when using plasma treatment, the redistribution of Ga and Al at the AlGaN–GaN interface i.e. in the channel area. Using Auger measurements near the SiON–AlGaN interface from the side of the insulator, the localization of nitrogen atoms chemically bonded with silicon N(Si) with the formation of a peak at the interface, the size of which increases with increasing duration of plasma exposure.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нитридные структуры</kwd><kwd>низкоэнергетическая азотная плазма</kwd><kwd>поляризационный заряд</kwd><kwd>глубокие центры канальные электроны</kwd><kwd>Оже-исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nitride structures</kwd><kwd>low-energy nitrogen plasma</kwd><kwd>polarization charge</kwd><kwd>connection of central electron channels</kwd><kwd>Auger studies</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают глубокую признательность за помощь в проведении экспериментальных работ и за участие в обсуждении полученных результатов старшему научному сотруднику Э.М.
