Growth of a three-dimensional anisotropic lattice of Ge quantum dots in an amorphous alumina matrix

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.

Tuning the growth properties of Ge quantum dot lattices in amorphous oxides by matrix type

A strong influence of matrix type on self-assembled growth of three-dimensional Ge quantum dot lattices in amorphous oxide matrices is demonstrated. An interplay between quantum-dot-related surface features and smoothing tendency of the matrix determines the type and quality of Ge quantum dot ordering.

Co nanocrystals in amorphous multilayers - a structure study

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.
