The study shows for the first time the effect of preformed alloying Al layer deposited on silicon substrate upon the morphology and orientation growth of ZnO:Al nanocrystals array. The stages of decay of the alloying Al layer into droplets of the quasi-liquid phase, from temperature treatment at the initial stage of the growth according to the vapor-liquid-crystal (VLC) mechanism, are demonstrated. The schema of growth stages of ZnO nanocrystals according to VLC mechanism, on Si substrate with a pre-applied layer of the alloying metal, is presented.

The grains structure of samples of а SmS targets, obtained by pressing methods without and with the use of subsequent high-temperature processing by high- frequency currents (further HFC), under various pressure was investigated. The density of samples obtained under different conditions was determined. The optimal technological conditions for obtaining high-quality targets of a samarium monosulfide are determined: high-frequency annealing with pressing under pressure of 5t/cm 2 is more effective than high-frequency current annealing with pressing under pressure of 4 t/cm 2 . A significant content of unbound metallic samarium in samples obtained by pressing at 5 t/cm 2 but not subjected to high-temperature HFC annealing has been established.
