Xps Definition and 14 Threads

I am new to XPS Data analysis, and I have a .sle file that I got out of XPS Machine Software, and I am using CasaXPS to analyse the data. This software takes only .vms files. I want to convert the .sle to a .vms file for analysis. How or where can I do this? Any help on this will be deeply...

I've had this MBP for 7 years now and it's done everything I could've asked of it. Things are starting to slow down now though, and small tasks are taking a good amount of time. I figured with my FAFSA money I would get a new laptop. I'm looking at the Dell XPS 13 and the MBP 13. I've been...

Homework Statement Hello, I am using CasaXPS to model synthetic peak models for X-ray photoelectron spectroscopy data. I am fitting. The software has a lot of manuals online but they do not explain how they yield a Residual Standard Deviation, after each fit iteration. Most software use...

Hello, I am trying to create peak models for some XPS spectra. I have a decent intuition of the chemistry of the samples, and I obtain really good residual standard deviation values for the modeled data; however, some of the FWHM of the modeled oxidized species (C and P) on the narrow scans are...

I work at a university and we recently had an XPS donated with a mass spec attachment. It is an older instrument that we would love to get working due to the high resolution detector and in situ reduction chamber. We are having issues getting the mass spec to communicate with the gassworks...

I propose the Pauling Scale is not valid in all circumstances, and other scales of electronegativity would do better to predict the behavior of electron density in molecules: Electronegativity seems to be poorly defined for such a widely used chemical property: a 'tendency' of an atom or...

How can we distinguish between Auger and core-level loss peaks (such as in XPS) in the secondary electron spectrum?

Dear All, for different oxidation states of the same element in X-ray photoelectron spectroscopy measurements, should the full width half maximum (FWHM) value be the same for all? Is this a parameter to fix in this case for the fitting? I am studying an amorphous transition metal oxide thin...

I've heard any many places that the density of states (DOS) can be determined from an x-ray photoelectron spectroscopy (XPS) spectrum. Perhaps someone more knowledgeable than me can explain how this is done, or can direct me to a good resource? Thanks!

Can someone help explain the difference between EDX(Energy-dispersive X-ray spectroscopy) vs. (XPS) X-ray photoelectron spectroscopy? Which is used for what application? Advantages/Disadvantages of each? From what I have been reading from documentation, they seem to be the same. Thanks.

Hi, guys! Gold is usually used as reference element to calibrate the detector in XPS due to the charge effect, why is Gold so specific? So what element can be the reference element for XRF and LIBS? Thanks a lot!

Hi everyone, i have a doubt regarding XPS, i read that a doublet is formed, for example in argon when an electron from 2p orbital leaves and leads to the formation of 2p 3/2 and 2p 1/2 states, and an electron with slightly lesser energy than one in the 2p orbital is emitted, giving rise to...

I wonder if anyone have an idea about the software (CASA) used for the treatement of data dounded by XPS analysis. If yes, I am in need to know how to remove the satellite peaks that may show in a spectrum. thanks

Hi guys, is there anyone who familar with xps? For Ni satellite, why the 2p1/2 satellithe only about 4.6ev? thx
