The imaging methods used at the ANKA Synchrotron Light Source (Institute for Synchrotron Radiation, Karlsruhe Institute of Technology) are briefly reviewed. Examples of recent applications of the phase-contrast imaging method using a grating interfer

We have performed small- and large-angle x-ray scattering experiments on CdTe/MnTe superlattices. The Fresnel optical method and the distorted wave Born approximation were used to extract from small-angle measurements out-of-plane and in-plane inform

A method for computation of X-ray grazing-incidence diffraction (GID) in multilayers and superlattices is presented. The method is based on X-ray dynamical diffraction theory and a matrix from a boundary equations and provides a simple numerical solu

The authors have studied a binary (AlAs/GaAs) multilayer structure and a short-period ternary (AlGaAs/GaAs) superlattice with a central enlarged GaAs single quantum well grown by molecular beam epitaxy (MBE) and by means of X-ray diffraction (XRD) (i

Our goal was to determine whether responses of cerebral arterioles are altered in aged rats. We examined responses of cerebral arterioles in adult (6-8 mo old) and aged (22-24) mo old) Wistar rats to superfusion of acetylcholine and bradykinin, which

An ultrathin silicon layer (16 nm) bonded onto a silicon wafer is studied by grazing incidence x-ray diffraction. We measure satellite peaks around the {220} reflections coming from two periodic dislocation networks localized at the bonding interface

Symmetrically strained superlattices on off-oriented substrates are studied by x-ray grazing incidence diffraction in order to investigate compositional ordering separately from the related lattice strain correlation depending on the lattice mismatch

Single and multilayer surface gratings of the system GaInAs/InP are studied by x-ray diffraction reciprocal space mapping. From the diffraction data we determine the grating period and shape, the vertical compositional set-up and the non-uniform stra

Multilayered gratings have been investigated by high-resolution grazing incidence diffraction, employing non-coplanar triple crystal diffractometry. A theoretical treatment has been developed based on the distorted wave Born approximation for multila
