Based on regular porous polymeric membranes, the synthesis of metallic and dielectric spearhead structures with given morphological characteristics was carried out. Copper structures with 1 μm height and dielectric spearhead microstructures made of iodoic acid with 12 μm height and 1 μm diameter of were obtained. The possibility of using such optical elements to solve the problems of increasing the efficiency of IR radiation detection, signal amplification and conversion to visible and near-infrared ranges.
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.
AbstractA method for forming regular dielectric and metallic microstructures based on polyethylene terephthalate films irradiated with a synchrotron radiation source through a mask with subsequent etching. To study their geometric parameters, scanning electron microscopy was used.
