Study on structural and optical properties of TiO 2 ALD coated silicon nanostructures
2016
Structural and optical properties of TiO2 ALD coated silicon nanostructures were investigated. The morphology and
chemical composition of TiO2 coated silicon nanopillars and porous silicon were studied by using methods of scanning
electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). Optical characteristics were studied using
measurements of reflectance and luminescence spectra. Detailed analysis of morphological features and
photoluminescence mechanisms were provided. Peculiarities of reflectance spectra were discussed. It was shown the
possible application of these structures as antireflectance coatings.
