Oct 1, 1997 · XPS measurements have been performed on a series of Mg II salts (NO 3−, CO 32−, SO 42−, Cl −, CH 3 COO −), hydroxides and oxides, these latter compounds are both commercial and prepared in laboratory.

Oct 1, 2024 · X-ray photoelectron spectroscopy (XPS) was used to investigate the oxidation states of the prepared samples. The Fe-doped MgO-NPs exhibited the highest value of oxygen vacancy states, indicating more defects compared to the other samples.

May 1, 2019 · Our final results are 529.5 eV for the O1s CEBE and 1303.5, 87.7 and 48.8 eV for Mg1s, Mg2s, Mg2p, respectively (all relative to the Fermi level). They agree with recent experimental XPS data within about 0.5 eV.

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections.

Jan 27, 2022 · Once the many-body effect is taken into account, there is good agreement between theory and the XPS measurement. The character of this atomic many-body effect is established in terms of a nearly degenerate configuration that is needed to describe the wavefunction when an Mg 2s electron is ionized.

Oct 3, 2016 · Instrumentational developments in the past two decades have popularized ambient pressure XPS, with pressures in the tens of mbar now commonplace. Here, we briefly review the technique, including a discussion of developments that allow data collection at higher pressures.

Once the many-body effect is taken into account, there is good agreement between theory and the XPS measurement. – The character of this atomic many-body effect is established in terms of a nearly degenerate configuration that is needed to describe the wavefunction when an Mg 2s electron is ionized.

MgO nanoparticles surface elements, state of valence and binding energy were determined from X-ray Photoelectron Spectroscopy (XPS). The XPS observation Fig. 5a.

Jan 3, 2021 · In an XPS graph, it is possible to see Auger electron peaks, such as O(KLL) and Fe (LMM). These peaks are usually wider in an XPS spectrum. Moreover, the KLL signal of MgO layers can be observed in the survey spectra of multilayer films.

12 hours ago · Feng et al. [11], through XPS and TEM analysis, found that the oxide film formed in the early stages of oxidation was mainly composed of Al 2 O 3. As time progressed, Mg gradually migrated toward the surface, forming MgO and a small amount of MgAl 2 O 4, thus revealing the mechanism of
