The Si3N4/TiN Interface: 7. Ti/TiN(001) Grown and Analyzed In situ using X-ray Photoelectron Spectroscopy
X-ray photoelectron spectroscopy (XPS) was used to analyze Ti/TiN(001) bilayers grown by ultrahigh vacuum reactive magnetron sputter deposition on MgO(001), with an electrically floating substrate potential of 7 V, in mixed 1:1 Ar/N2 discharges maintained at a total pressure of 0.5 Pa (3.75 × 10-3 Torr). The TiN(001) films were grown at 600 °C and the 4-ML-thick Ti overlayers at room temperature. XPS spectra were obtained using incident monochromatic Al Kα x-radiation at 0.83401 nm. Ti/TiN(001) Ti 2p spectra reveal reduced unscreened final-state satellite peaks compared to Ti 2p spectra obtained from uncapped TiN(001) due to increased electronic screening. © 2012 American Vacuum Society.
