High-resolution X-ray diffraction in coplanar and noncoplanar geometries has been used to investigate the influence of an SiNx nano-mask in the reduction of the threading dislocation density of high-quality AlGaN epitaxial layers grown on sapphire substrates.

A self-assembly process is demonstrated that results in the formation of an anisotropic lattice of regularly ordered Ge quantum dots in an amorphous alumina matrix. The prepared material shows a strong anisotropy of the electrical transport properties.
Keywords: Ge quantum dots; self-assembly; conductivity; anisotropy; magnetron sputtering; synthesis.

Periodic Co/SiO2 multilayers deposited by magnetron sputtering were investigated by grazing-incidence small-angle X-ray scattering, X-ray diffraction and the time-of-flight elastic recoil detection analysis method. During the deposition, Co nanoparticles are created and order spontaneously, forming a three-dimensional periodic array.
