Epitaxial growth of column-like nanostructures InGaN on Si in poromeric anodic alumina

Abstract

Method of formation of regular PAA without a barrier layer in the process of anodizing of Al-film on n-type Si has been developed. Semiconductor InGaN-structures were selectively grown in modified PAA-template by MO VPE. Formed self-organized nanostructures InGaN have nonpolar crystallographic α-orientation. Investigations of luminescent properties and analysis of the spectral characteristics have been performed.
