Каждый rt-дефект вносит два уровня энергии в энергетическую щель (запрещенную зону) кристаллической матрицы и может находиться в одном из трех зарядовых состояний (−1, 0, +1). Такой диод, в котором отсутствуют и электроны в c-зоне, и дырки в v-зоне, называется ζ-диодом. Ток в ζ-диоде осуществляется только посредством прыжков электро-нов между rt-дефектами. В дрейфово-диффузионном приближении численно решена система стационарных нелинейных дифференциальных уравнений, описывающая прыжковую миграцию электронов по rt-дефектам. Рассчитаны статические вольт-фарадные характеристики ζ-диода на основе кристаллического кремния для интервала рабочих температур от 78 до 373 К. Отмечена возможность использования ζ-диодов в качестве радиационно-стойких варикапов, работающих при низких (криогенных) температурах.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title> </title><p> </p><p>For the ﬁrst time the capacitance of a semiconductor p+n+-diode is theoretically calculated, in which both the p+-region and the n+-region are completely compensated with point irradiation-induced defects (rt-defects) of one kind. Each rt-defect introduces two energy levels into a band gap of crystalline host matrix and can be one of three charge states (−1, 0, +1). Such a diode, in which both electrons in the conduction band and holes in the valence band are absent, is called a ζ-diode. The ζ-diode current is performed by electron hopping via rt-defects only. In the drift-diffusion approximation, a system of stationary nonlinear differential equations for hopping migration of electrons via rt-defects is numerically solved. The static capacitance-voltage characteristics of the ζ-diode based on crystalline silicon are calculated for the operating temperature ranging from 78 to 373 K. It is shown that the ζ-diode can be used as radiation-resistant varicaps operating at low (cryogenic) temperatures.</p></sec><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>трехзарядные радиационные дефекты</kwd><kwd>прыжковая миграция электронов</kwd><kwd>дрейфово-диффузионное приближение</kwd><kwd>полупроводниковый диод</kwd><kwd>дифференциальная электрическая емкость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>triple-charged irradiation-induced defects</kwd><kwd>hopping migration of electrons</kwd><kwd>drift-diffusion approximation</kwd><kwd>semiconductor diode</kwd><kwd>differential capacitance</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">Поклонский, Н.
