Description

It is proposed to use qualitative investigation methods of the differential Takagi equation solutions for the analysis of general properties of wave fields in deformed crystals. The physical interpretation of possible types of the Takagi equation solutions is considered briefly from the viewpoint of the stability theory. The type of solutions are defined by ratios between parameters involved in the equations set. For the Takagi equation these parameters are prescribed by the angular tuning from the precise Bragg angle as well as structural characteristics of the crystal and the deformation profile. The qualitative analysis for the problem of the dynamic X-ray diffraction is carried out for films with the variable deformation gradient and superlattices

Abstract (Russian)

Для анализа общих свойств волновых полей в деформированном кристалле предлагается использовать качественные методы исследования решений дифференциальных уравнений Такаги. Кратко рассмотрена физическая интерпретация возможных типов решений уравнений Такаги с позиций теории устойчивости. Тип решений определяется соотношениями между параметрами, входящими в систему уравнений. Для уравнения Такаги эти параметры задаются угловой отстройкой от точного угла Брэгга и структурными характеристиками кристалла и деформационного профиля. Проведен качественный анализ задачи динамической рентгеновской дифракции для пленок с переменным градиентом деформации и для сверхрешеток
