Analysis and Results
X-ray Photoelectron Spectroscopy (XPS)
The sample was mounted on a glass substrate using double tape. Three different spots per sample were analyzed. Parameters were set as follows, X-Ray source: Monochromatic Al Ka (1486.6 eV), Spot size: 900 um. Survey scans and high resolution scans were collected with pass energies of 150 and 20 eV and with a step size of 1.0 and 0.05 eV. Detailed spectra processing was performed by Thermo Avantage (5.982) software
