example: A*1 (peak will be the same width as peak A) Pos. example: 285.00, 285.45) or a simple mathematical formula (fwhm Constr. These can either be a range of values (fwhm Constr.example:1, 2.5 Pos. You can add peak constraints by entering values into the Area Constr., fwhm Constr. Add more peaks as needed using the Create button.ĥ. You can drag and move the peak using the mouse if desired or you can position and change the parameters of the peak by adjusting the Area, fwhm and Position values.Ĥ. Under the Components panel click on Create to create a peak.
The starting and endpoints of the region can also have an offset applied to them by changing the St. For other available backgrounds see the CasaXPS manual. To change the type of background type S for a Shirley background in the BG Type box, type L for a linear background, or T for a Tougaard background. Drag the endpoints to the desired location. Click on the Quantification Parameters button and go to the Regions panel.Ģ.
Although the latter satellites have been discussed by many authors, the former satellites are first reported here.1. The others are classified into two kinds of satellite peaks, whose energy separation from the main peaks are 3 and 13 eV. Two of them are main peaks of Ti2p 3/2 and 2p 1/2. Peak separation of the deconvoluted spectrum reveals that it has six peaks. The replacement of the non-energy loss peak of O1s with narrower Gaussian peak takes off the beat waves. When the raw O1s spectrum is used as the response function, the deconvoluted spectrum has negative intensity values in some regions and beat waves. FWHM of the non-energy loss peak of Ti2p 3/2 is smaller than that of O1s.
It indicates that O1s XPS is proper as the response function to deconvolute a Ti2p spectrum. The features of inelastic scattering peaks in EELS were more influenced by surface than O1s XPS. Ti2p and O1s XPS spectra of a clean surface of single crystal TiO 2 fractured in situ were taken to study the removal of the inelastic scattering part from the Ti2p spectrum.
