Paper Abstract

The aim of the work is to apply the Auger Electron Spectroscopy to determine the chemical composition and uniformity of silica-titania SiO2:TiO2 waveguide films which were fabricated via sol-gel method. The SiO2:TiO2 waveguide layers are routinely produced on glass substrates, however, for the research presented in the paper, they were made on silicon substrates. We registered series of 50 Auger spectra on the different depths in the structure. The result show that the structure is chemically and structurally uniform through the whole depth.
