| Abstract: | Показано, что общепринятые модели электронной структуры ряда радиационных дефектов в кремнии не являются адекватными. Для прогностического моделирования характеристик облученных кремниевых детекторов частиц требуется их пересмотр. |
| Abstract (in another language): | The validity of a single-level model to interpret temperature dependencies of charge carrier concentration in n-Si crystals irradiated by Co-60 gamma-rays is investigated. It is shown that the consideration of a vacancy-oxygen complex (the A-center) in silicon as a isolated monovalent defect vi/ith energy level close to Ec-0.17eV does not allow to describe adequately Hall effect data for crystals in which the A-center is dominant. From carbon related complexes the single-level model is adequate only for interstitial carbon C. The explanation of experimental data for a CrCs complex requires more complex models. The acceptable description of experimental dependencies of n(T) can be achieved only within the framework of various two-level models. However the acceptance of any of them entails a conclusion that the investigated radiation defects are coupled in pairs even at very low irradiation fluences. |
