Here we employ a solid-state Li4+xTi5O12/LiPON/LixV2O5 cell and examine in situ the chemistry of Li-O2 reaction products on LixV2O5 as a function of applied voltage under ultra high vacuum (UHV) and at 500 mtorr of oxygen pressure using ambient pressure X-ray photoelectron spectroscopy ...
b) Schematic representation of the size effect on the gap between the valence band (VB) and the conduction band (CB) and the absorption (up arrow) and fluorescence (down arrow). Smaller particles have a wider band gap. . 6 1.2 X-ray Photoelectron Spectroscopy (XPS) ...
SURFACE ANALYSIS | X-Ray Photoelectron Spectroscopy S. Tougaard, in Encyclopedia of Analytical Science (Second Edition), 2005 Instrumentation for XPS The illustration of Figure 10 is a schematic diagram of a commercial electron spectrometer. The essential features are an X-ray source, the specimen,...
Device fabrication: A schematic and a photograph of the sample holder for in-operando X-ray absorption measurement are shown in Fig. S1, respectively. The sample holder was made of PEEK (polyetheretherketone) with two metal screw electrodes for bias control. After connecting the cathode and anode...

X-ray photoelectron spectroscopy (XPS) is a proven tool to obtain information about local charge with atomic specificity in electronic ground states5. The tight localisation of core orbitals makes the method site selective. The ionisation potential (IP) measures the difference between neutral state an...
X-rays are also used in the inspection of a semiconductor device, especially an ultra LSI (large Scale Integrated Circuit) by elemental analysis or X-ray photoelectron spectroscopy (XPS) with characteristic X-rays or fluorescent X-rays. For example, the Japanese laid open patent application JP ...
