fields of study / plans the course is directly associated with
Course objectives
The goal of this course is to allow the students to
- list and describe basic properties of x-ray diffraction and x-ray reflection at thin films
- apply the knowledge to a study of defects in semiconductor heterostructures and their interfaces
Syllabus
  • 1. Basic description of an x-ray wavefield x-ray wave in vacuum the Green function of a free particle, its plane-wave representation Wave scattering, scattering cross-section Directions of the scattered waves Classification of the scattering theories 2. Kinematical scattering from ideal structures scattering from an atom scattering from a small crystal scattering from a thin layer, x-ray diffraction, x-ray reflection Absorption and refraction corrections 3. Kinematical x-ray diffraction from disturbed thin layers Homogeneous deformation, pseudomorph and relaxed structures periodic superlattices random deformation, coherent and incoherent scattering scattering from lateral structures 4. Dynamical scattering theory Wave equation for a crystal dispersion surface boundary conditions at the crystal surface one-wave approximation , x-ray reflection two-waves approximation, x-ray diffraction non-coplanar arrangement 5. X-ray reflection from rough interfaces statistical description of the roughness fractal roughness self- assembled structures coherent and diffuse scattering from rough interfaces 6. Experimental aspects x-ray sources x-ray monochromators, diffractometers resolution function in reciprocal space x-ray detectors
