XPS STUDY OF THE NITRIDES, OXIDES AND OXYNITRIDES OF TITANIUM

X-ray photoelectron spectroscopy is employed for the study of compositions and electronic-structure peculiarities of the powder-like titanium oxynitrides, including the compositions TiN0.96 and TiO1.03. The corresponding spectra from the core electron level and valence bands are obtained and interpreted. The conclusion is drawn that the anomalous concentration dependences of the properties of TiN-TiO system solid solutions are associated with the corresponding changes of the electron-energy spectrum.
