High-energy x-ray photoelectron spectroscopy spectra of TiO2 measured by Cr Kα

Titanium oxide (TiO2) grown by physical vapor deposition (PVD) on Si was analyzed using high-resolution high-energy x-ray photoelectron spectroscopy (HAXPES). The HAXPES spectra of TiO2 obtained using monochromatic Cr Kα radiation at 5414.8 eV include two survey scans (Al Kα and Cr Kα) and high-resolution spectra of Ti 1s, Ti2p, Ti 2s, Ti 3p, Ti 3s, and O 1s.
