Auger Electron Spectroscopy for Chemical Analysis of Passivated (Al,Ga)N-Based Systems [PDF]

open access: yesMicromachines
This review summarizes the use of Auger Electron Spectroscopy (AES) for microchemical analysis of two different types of dielectric/(Al,Ga)N-based systems: (i) extrinsic dielectric PECVD SiO2, ALD Al2O3, and ECR-CVD SiNx films on AlxGa1−xN/GaN structures

Positron Annihilation Induced Auger Electron Spectroscopy [PDF]

open access: goldAIP Conference Proceedings, 2022
A review is given on the results of PAES (positron annihilation induced Auger Electron Spectroscopy) studies to data, with a concentration on those results obtained at the University of Texas at Arlington. Low energy positions, trapped in a surface localized state annihilate with core electrons resulting in the emission of Auger electrons.

High-resolution electron–multi-ion coincidence set-up for gas-phase experiments in the tender and hard X-ray range [PDF]

open access: yesJournal of Synchrotron Radiation
The MUSTACHE setup (MUlti-STep photofragmentation studies by Auger electron–ion Coincidences using High Energy photons) is a high-resolution electron–multi-ion coincidence system optimized for gas-phase experiments in the tender (∼2–10 keV) and hard (>5 ...

AUGER ELECTRON SPECTROSCOPY OF ALLOY SURFACES [PDF]

open access: greenFaraday Discussions of the Chemical Society, 1975
Regular solution models predict surface segregation of the constituent of lowest surface free energy in homogeneous multicomponent systems. Analysis of the Auger electron emission intensities from alloys yield the surface composition and the depth distribution of the composition near the surface. Auger Electron Spectroscopy (AES) studies of the surface

Enhanced intermolecular coulombic decay due to sulfur heteroatoms in thiophene dimer [PDF]

open access: yesCommunications Chemistry
Intermolecular Coulombic decay (ICD) is an important relaxation process of excited atoms and molecules in an environment, producing low-energy electrons that may contribute to radiation damage.

Ambient pressure X-ray absorption spectroscopy at ME2-BL02B of SSRF and its application in catalysis

open access: yesHe jishu, 2021
BackgroundThe traditional soft X-ray absorption spectroscopy (XAS) method can only work under ultra-high vacuum conditions and cannot be used to detect changes in the electronic structure of samples under real conditions.

Separation of surface oxide from bulk Ni by selective Ni 3p photoelectron spectroscopy for chemical analysis in coincidence with Ni M-edge Auger electrons

open access: yesScientific Reports, 2021
The chemical shift of core level binding energies makes electron spectroscopy for chemical analysis (ESCA) a workhorse analytical tool for science and industry. For some elements, close lying and overlapping spectral features within the natural life time
