![]() We can do this by masking and selecting the data before averaging. The fitting of XPS photoelectron spectra is often used to determine the relative amounts of different chemical states contributing to a spectrum. The first component corresponds to a \(\text_2\) region, as identified by Component 0. For the fit, a variety of peak and background models are or will be. Very intense locations in the spatial maps correspond to places where the spectrum on the right is a good representation to the data (red) or to its negative (blue).īased on the images, we can see that the first four components (0 through 3) explain almost all the variation in the data. Fitting for XPS (x-ray photoelectron spectra) (rewrite of schachmett/xpl) - GitHub. Each row above has a spatial map of the coefficient in the decomposition (left) and the XPS spectrum corresponding to that component (right). A Comprehensive Software Stack for Condensed Matter Physics.Converting Time-of-Flight Data to Kinetic Energy.There are several ways to do it but I found this is the best way to do it quickly and easily. Understanding ARPES: the Single Particle Spectral Function The simplest but effective way of multiple peaks fitting of XPS, Raman, Photoluminesence spectroscopic data/graph.Understanding ARPES: Momentum Conversion.Adding Support for Beamlines or Lab Facilities.More advanced plotting techniques in PyARPES.Looking at the wider vs narrower peak regions.Selecting data using the PCA decomposition.
