Содержание второй компоненты в кристалле диаметром 15 мм и длиной 40 мм, выращенном модифицированным методом плавающей зоны из шихты составом 79,8 % (ат.) Si и 20 % (ат.) Ge и с добавками 0,2 % (ат.) бора, исследовано с помощью метода рентгеновского микроанализа как в отдельных точках образца, так и в режиме линейного сканирования вдоль оси кристалла и поперек. Установлено, что продольное изменение концентрации германия хорошо описывается аналитически уравнением, выведенным ранее для условий роста из тонкого слоя расплава монокристалла Ge, легированного примесью Sb или Ga, в присутствии погруженного в расплав нагревателя. Для более точного описания экспериментальных данных был проведен учет изменения толщины слоя расплава между растущим кристаллом и дном погруженного нагревателя по мере кристаллизации. Показано, что поперечное распределение второй компоненты, которое не превышало 5 % по диаметру, может быть существенно улучшено за счет уменьшения кривизны фазовой границы в процессе роста. </p></abstract><trans-abstract xml:lang="en"><p>We studied experimentally and theoretically the possibility to obtain a uniform single crystal of SiGe alloy enriched at the Si side. The content of the second component in a crystal 15 mm in diameter and 40 mm in length grown by the modified floating zone technique from the charge of 79.8 at.% Si and 20 at.% Ge composition with 0.2% B admixture has been investigated using selected area X−ray analysis in different points and in line scanning mode along and across the crystal axis. The longitudinal changes in the germanium concentration of proved to be well described by the analytical equation previously derived for conditions of Sb (Ga) doped Ge growth from a thin melt layer in the presence of a heater submerged into the melt. For a more accurate description of the experimental data we made allowance for the change in the melt layer thickness between the growing crystal and the bottom of the submerged heater. The lateral distribution of the second component, not exceeding 5% over a diameter of the crystal, can be significantly improved by reducing the curvature of the phase interface during the growth. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>установка и выращивание кристаллов модифицированным методом вертикальной зонной плавки</kwd><kwd>погруженный в расплав нагреватель</kwd><kwd>кремний</kwd><kwd>сплав с германием</kwd><kwd>рентгеновский микроанализ</kwd><kwd>однородность кристалла</kwd></kwd-group><kwd-group xml:lang="en"><kwd>setup and modified floating zone technique of crystal growth</kwd><kwd>submerged into the melt heater</kwd><kwd>silicon</kwd><kwd>alloy with germanium</kwd><kwd>X−ray microanalysis</kwd><kwd>crystal homogeneity</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">Abrosimov, N.
