Показано, что абсолютные значения изученных характеристик возрастают при увеличении температуры. На кривых σ = f(T) обнаружены участки с разным наклоном, что свидетельствует о наличии нескольких типов проводимости в исследованных полупроводниках. Выявлена дисперсия диэлектрических свойств исследованных монокристаллов: с ростом частоты значения диэлектрической проницаемости уменьшаются, а удельной электропроводности – увеличиваются. Обнаружено существенное влияние облучения электронами на электропроводность и диэлектрическую проницаемость исследованных монокристаллов.Увеличение дозы облучения приводит к уменьшению диэлектрической проницаемости и значительному возрастанию электропроводности во всей исследованной области температур.</p></abstract><trans-abstract xml:lang="en"><p>The quaternary compound Cu2ZnSnS4 was synthesized by the one-temperature method from the elementary components. Single crystals of Cu2ZnSnS4 were grown by chemical gas-transmission. Samples were prepared in the form of plane singlecrystal plates with a size of more than 2×5×0.5 mm. The electrical conductivity and dielectric properties of Cu2ZnSnS4 single crystals are investigated in the temperature range 100–300 K at the measuring field frequencies of 103–106 Hz. Non-irradiated samples and those irradiated by electrons with an energy of 4 MeV and doses of 1015 and 1016 cm-2are studied. It is shown that the absolute values of the studied characteristics increase with temperature. The curves σ = f(T) have the areas with different slopes, which indicates the presence of several types of conduction in the investigated semiconductors. The dispersion of the dielectric properties of the studied single crystals is revealed: as the frequency is increased, dielectric constant values decrease and, as electrical conductivity is increased, these values grow. Increasing the radiation decreases dielectric permittivity and causes a significant growth of electrical conductivity in the entire investigated temperature range.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>четверные полупроводники</kwd><kwd>диэлектрическая проницаемость</kwd><kwd>удельная электропроводность</kwd><kwd>электронное облучение</kwd><kwd>дисперсия</kwd><kwd>низкотемпературные исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>quaternary semiconductors</kwd><kwd>dielectric constant</kwd><kwd>electrical conductivity</kwd><kwd>electron irradiation</kwd><kwd>low-temperature investigations</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">Compositional investigation of potassium doped Cu(In,Ga)Se2 solar cells with efficiencies up to 20.8 % / P.
