Выращены однородные монокристаллы твердых растворов Ge−Si с содержанием кремния от 0.2 до 0.8 ат%, легированные сурьмой. Методом инфракрасной фурье-спектроскопии в интервале температуры от 25 до 60 • С на длине волны 10.6 мкм исследовано оптическое поглощение монокристаллов с удельным электрическим сопротивлением 2−3 Ом · см. Установлено, что при введении кремния в Ge возрастает температурная стабильность оптических свойств кристаллов.
The radial distribution of mechanical stress, optical inhomogeneity and oxygen concentration in Sb-doped germanium crystals grown by the Czochralski method with diameter of 200 mm and resistivity from 10.5 to 18.5 Ω·cm were studied. It was found that residual stress calculated from the data of X-ray structural analysis correlates with results of numerical simulation of thermoelastic stress and interrelates with optical inhomogeneity and concentration of oxygen presented in the atomically dispersed state in germanium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
