✦ Synopsis

Two-dimensional Fourier transformation of AFM, SEM and TEM images of the surface of solids macro-and nanostructured by three different techniques (laser-controlled atomic beam deposition on a glass substrate, electrochemical etching of semiconductors and UV pulsed laser recrystallization of thin amorphous semiconductor films on a glass substrate) reveals the presence of a similar, hidden, long-range, quasi-hexagonal order in the spatial distribution of surface inhomogeneities (nanoparticles, pores and crystalline grains). The occurrence of the long-range quasi-hexagonal order and other experimental data are described on the basis of a general Defect-Deformational (DD) theory of the spontaneous formation of surface periodic DD macro and nanostructures.

In order to directly control the size and in particular the position ofnanostructures naturally formed on high-index semiconductor surfaces during molecular beam epitaxy (MBE) and metalorganic vapor phase epitaxy (MOVPE), the growth on patterned high-index GaAs substrates is investigated. During MBE
