Роль жидкого подслоя Al в качестве катализатора направленного роста нанокристаллов ZnO

Abstract

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.
