Аннотация

Abstract: Composites consisting of Ge nanoclusters embedded in GeO₂ matrix were modified by selective removal of the germanium dioxide in deionized water or HF. Thin (up to 200 nm) and thick (300−1500 nm) GeO₂{Ge-NCs} heterolayers were studied before and after the etching using Raman spectroscopy, scanning and spectral ellipsometry, scanning electron microscopy. It was found that a stable skeletal framework from agglomerated Ge nanoparticles (amorphous or crystalline) was formed after the etching of thin GeO₂{Ge-NCs} heterolayers. When removal the GeO₂ matrix from a thick GeO₂{Ge-NCs} heterolayer, released Ge nanoclusters were arranged in a vertically ordered chains.
