WebThe EELS recorded up to a few tens of electron volts is sometimes called the low-loss region. In general, the term “low-loss’’ is used to describe the energy-loss of electrons … WebMar 1, 2024 · The energy resolution of EELS analyses is often expressed in terms of the full width at half maximum (FWHM) of the ZLP [9]. In the low-loss region, the contribution from the ZLP often overwhelms that from the inelastic scatterings arising from the interactions of the beam electrons with the sample.

WebDec 31, 2024 · In the case of low-loss EELS spectrum, its shape reflects the effects of several factors including volume plasmon, surface plasmon, inter-band transition and semi-core state transition. In the case of high-loss spectrum, the overlap of ionization edges, chemical shift, change of white-line L 3 /L 2 ratio and near-edge fine structure can make it ... WebOct 7, 2024 · EELS. EELS characterization was performed to complement selected area electron diffraction (SAED) results. Low loss EELS spectra from areas of interest were extracted from exposed and quenched FIB-prepared TEM samples; Fig. 2 shows the low loss EELS spectra for α-Zr, δ-hydride, and the α/δ interface. The extracted spectra for … theodoret ecclesiastical history

WebSep 17, 2024 · Using electron energy-loss spectroscopy (EELS) within a monochromated scanning transmission electron microscope (STEM) on the highest-quality crystals available, we demonstrate unequivocally that the optical-gap energy of c -BN slightly exceeds 10 eV. WebExploiting the information provided by electron energy-loss spectroscopy (EELS) requires reliable access to the low-loss region where the zero-loss peak (ZLP) often overwhelms … WebMay 2, 2024 · Further analysis of the metal-semiconductor interface using Energy Electron Loss Spectroscopy (EELS) showed that the amount of oxides (In x O y, Ga x O y or As x O y) was significantly decreased for the etched samples. These results suggest that the low contact resistance obtained after digital etching is attributed to the combined effects of ... theodore t.c. calvin
