| Popis | The paper is organized as follows. In the second part the X-ray diffraction theories for studying SLs will be presented. In the third part both the kinematical theory and the semi-kinematical approximation of dynamical theory will be used to calculate both the positions and the intensities of the diffraction peaks of the Fibonacci SL by the Fourier transform treatment and by an exact treatment. The diffraction curve of Fibonacci SL will be compared with that of a periodic SL. Diffraction patterns of other types of aperiodic superlattices will be reviewed briefly. The fourth part concerning X-ray reflectivity will demonstrate the equivalence between the reflectivity and diffraction. In the last section the idea of a Fibonacci grating will be proposed and the reciprocal space intensity distribution will be kinematically calculated. |
