During a XPS study of oxide growth and segregation on commercial aluminium-silicon alloys, problems were encountered in the application of Cls charge referencing. Using the Cls peak maximum as a reference, shifts were observed in the aluminium and magnesium peak positions, particularly after high ...
Based on further analysis of the elemental XPS spectra, it can be determined that the insertion and release process of Al3+ in the laminar structure of the heterojunction surface is one of the reasons for providing the higher specific capacity of the battery. The mechanism diagram of the MoS2...

A sensitive XPS surface elemental composition confirmed the formation of the PEALD Al2O3 ultra-thin film with an Al 2s peak at 119.2 eV, Al 2p peak at 74.4 eV, and was oxygen rich. The SEM analysis presented a non-uniformity of around 3%. Finally, the rubidium consu...
A simple approach to estimating the detection limits of X-ray photoelectron spectroscopy (XPS) for any element in any elemental matrix is presented, using the intensity of the background at the expected position for the photoelectron peak to be detected. The approach has been extended to estimate...
High resolution XPS data of the O 1s peak and onset of elastic losses were used to establish the (Al0.14Ga0.86)(2)O-3 bandgap to be 5.0 +/- 0.30 eV. The valence band offsets were -0.25 eV +/- 0.07 eV and 0.05 +/- 0.02 eV for CuI on Ga2O3 or (Al0.14Ga0.86)(2)O-3, ...
X-Ray photoelectron spectroscopic (XPS) analysis of the lanthanum containing gels, heated to 500 and 1000 °C, shows a peak at 836.5 eV for La 3d5/2, which could be due to the presence ofMMOMAl type bridges in the samples.The contribution of m+ in the Ce 3d peaks suggests that both...

And the peaks of CO after the first peak were attributed to the regional combustion of the CB, which was not in contact with catalyst particles. The fresh 3Pt5Mn was estimated to the oxidation states on the catalyst surface by XPS. For used sample at 700°C, the BEs of Pt 4d5 was ...
XPSAl coordinationAl KLL Auger peakThe chemical state of Al at the surface of dealuminated mordenites has been investigated by X-ray photoelectron spectroscopy. The Al 2p peaks can reasonably be decomposed into two components. The Al KLL Auger transition is more sensitive to the Al coordination,...
