Рассматриваются комнатные температуры (T ≈ 300 К), когда в отсутствие подсветки для a-Si:H преобладает прыжковый механизм миграции электронов между точечными дефектами структуры. Для такого конденсатора рассчитаны зависимости электрической емкости от частоты измерительного сигнала ω/2π в диапазоне от 0,1 до 300 Гц для слоя a-Si:H cо стационарной прыжковой электропроводностью σdc ≈ 1 ∙ 10−10 (Ом ∙ см)−1. Считалось, что при малосигнальном режиме измерения емкости сквозного переноса электронов между слоем a-Si:H, слоями диэлектрика и обкладками конденсатора нет. Показано, что действительная часть емкости конденсатора уменьшается с увеличением угловой частоты ω, а мнимая часть отрицательна и немонотонно зависит от ω. Уменьшение действительной части емкости конденсатора до геометрической емкости последовательно соединенных оксидных слоев и слоя a-Si:H при увеличении ω обусловлено уменьшением электрического сопротивления конденсатора. Вследствие этого с увеличением ω мнимая часть емкости шунтируется прыжковой электрической проводимостью конденсатора. Определен сдвиг фаз для подаваемого на конденсатор синусоидального электрического сигнала в зависимости от частоты ω/2π в диапазоне 0,1–300 Гц для значений электропроводности слоя гидрогенизировнаного аморфного кремния σdc ≈ 1 ∙ 10−11; 1 ∙ 10−10; 1 ∙ 10−9 (Ом ∙ см)−1 при температуре 300 К. С увеличением электропроводности σdc слоя a-Si:H минимальное абсолютное значение угла сдвига фаз (≈65°) сдвигается в область высоких частот (от 1 до 100 Гц). Предложенный конденсатор может найти применение в электрических цепях регистрации низкочастотных сигналов для целей биомедицины.</p></abstract><trans-abstract xml:lang="en"><p>We propose a structural and electrical schemes of a capacitor based on a 3 μm thick a-Si:H (amorphous hydrogenated silicon) layer separated from the metal plates by 0.3 μm thick dielectric layers of SiO2 (silicon dioxide). We consider room temperatures (T ≈ 300 K) when in the absence of illumination for a-Si:H the hopping mechanism of electron migration via point defects of the structure prevails. For such a capacitor, the dependencies of the capacitance on the frequency of the measuring signal ω/2π in the range from 0.1 to 300 Hz are calculated for the a-Si:H layer with stationary hopping electrical conductivity σdc ≈ 1 ∙ 10−10 (Ohm ∙ cm)−1. It is assumed that there is no end-to-end electron transfer between the a-Si:H layer, dielectric layers and capacitor plates in the small-signal mode of capacitance measurement. It is shown that the real part of the capacitance of the capacitor decreases with increasing angular frequency ω, and the imaginary part is negative and depends non-monotonically on ω. The decrease in the real part of the device capacitance to the geometric capacitance of the series-connected oxide layers and the a-Si:H layer with increasing ω is due to a decrease in the electrical resistance of the capacitor. As a result, with increasing ω, the imaginary part of the capacitance is shunted by the hopping electrical conductivity of the capacitor. The phase shift for a sinusoidal electrical signal supplied to the capacitor is determined depending on the frequency ω/2π in the range of 0.1–300 Hz for the values of electrical conductivities of the hydrogenated amorphous silicon layer σdc ≈ 1 ∙ 10−11, 1 ∙ 10−10, and 1 ∙ 10−9 (Ohm ∙ cm)−1 at the temperature 300 K. With an increase in the electrical conductivity σdc of the a-Si:H layer, the minimum absolute value of the phase shift angle (≈65°) shifts to the high- frequency region (from 1 to 100 Hz). The proposed low-frequency capacitor can find application in electrical circuits for detecting low-frequency electrical signals for the purposes of biomedicine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гидрогенизированный аморфный кремний</kwd><kwd>диоксид кремния</kwd><kwd>низкочастотный конденсатор</kwd><kwd>электропроводность на постоянном и переменном токах</kwd><kwd>электрическая емкость</kwd><kwd>сдвиг фаз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrogenated amorphous silicon</kwd><kwd>silicon dioxide</kwd><kwd>low-frequency capacitor</kwd><kwd>electrical conductivity at direct and alternating currents</kwd><kwd>capacitance</kwd><kwd>phase shift</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана Государственной программой научных исследований «Материаловедение, новые материалы и технологии» Республики Беларусь.</funding-statement><funding-statement xml:lang="en">The work was supported by the Belarusian National Research Program “Materials Science, New Materials and Technologies”.</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">Физика гидрогенизированного аморфного кремния: пер. с англ. / под ред.
