The titanium Ti2p peak is notoriously difficult to fit. Let us first look for some clues in [[Specific Process Knowledge/Characterization/XPS/Processing/XPSknowledgeview |XPS Knowledge view]]. | The titanium Ti2p peak is notoriously difficult to fit.

The only challenge we are missing from this cocktail of asymmetric peak shapes, differences in spin-orbit splitting, reduction of fully oxidized Ti2p to sub-oxides and satellite features is the presence of TiN. | The only challenge we are missing from this cocktail of asymmetric peak shapes, differences in spin-orbit splitting, reduction of fully oxidized Ti2p to sub-oxides and satellite features is the presence of TiN. | ||
