Charge-induced chemical dynamics in glycine probed with time-resolved Auger electron spectroscopy [PDF]

open access: yesStructural Dynamics, 2022
In the present contribution, we use x-rays to monitor charge-induced chemical dynamics in the photoionized amino acid glycine with femtosecond time resolution.

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

Thickness determination of few-layer hexagonal boron nitride films by scanning electron microscopy and Auger electron spectroscopy

open access: yesAPL Materials, 2014
We assess scanning electron microscopy (SEM) and Auger electron spectroscopy (AES) for thickness measurements on few-layer hexagonal boron nitride (h-BN), the layered dielectric of choice for integration with graphene and other two-dimensional materials.

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 in the Scanning Electron Microscope: Auger Electron Images

open access: yesApplied Physics Letters, 1971
A two-dimensional surface chemical analysis over an area on a metal specimen has been accomplished by means of high-spatial-resolution Auger electron spectroscopy in a computerized scanning electron microscope. The experimental results are presented in graphic form by the new method of Auger electron imaging.

The adsorption behaviour of O2 on the clean Si(110) surface in the early stage [PDF]

open access: yes, 1987
This Letter reports on the early stage of adsorption of O2 on the clean Si(110) surface, showing a prominent 5×1 reconstruction, in ultrahigh vacuum at 300 K.

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.

Evidence for trap-assisted Auger recombination in MBE grown InGaN quantum wells by electron emission spectroscopy [PDF]

open access: yes, 2020
We report on the direct measurement of hot electrons generated in the active region of blue light-emitting diodes grown by ammonia molecular beam epitaxy by electron emission spectroscopy. The external quantum efficiency of these devices is
