Positron annihilation induced Auger electron spectroscopy [PDF]
, 1990 Recently, Weiss et al. have demonstrated that it is possible to excite Auger transitions by annihilating core electrons using a low energy (less than 30eV) beam of positrons.

Single‐Atom‐Enhanced Fully Inkjet‐Printed Electrochemical Sensor for Dopamine Detection
Advanced Science, EarlyView.Fully inkjet‐printed paper‐based dopamine sensors are fabricated using nitrogen‐doped graphene acid functionalized with copper single atoms. The copper sites uniquely enhance dopamine oxidation through strong molecular adsorption, as verified by electrochemical measurements and DFT calculations. The approach highlights the potential of single‐atom inks

Deconvolution in Auger Electron Spectroscopy [PDF]
, 1986 Deconvolution calculations have been applied in Auger Electron Spectroscopy to increase resolution and/or to eliminate loss features. We present: i) A short review of the methodology; ii) Recent results obtained in our laboratory in spectroscopy of Al ...

Charge neutrality level in significantly cation-anion mismatched semiconductors [PDF]
The fundamental bulk and surface electronic properties of a novel class of semiconductors, characterised by a significant mismatch between the size and electro-negativity of the cation and anion (SCAMS), have been investigated.

Advanced Science, EarlyView.Through quantitative ligand stripping of [Cu18H17(PR3)10]+ nanoclusters via intramolecular interaction modulation, selectivity for CO2 electroreduction to C2H4 is significantly enhanced. The weakly coordinating ligand triggers dual‐ligand stripping (FEC2H4 = 70.59%), whereas the strongly coordinating ligand results in single‐ligand retention (FEC2H4 ...

Engineering Slow‐Carrier Interfacial Recombination Enables Tailored Spectral Response
Advanced Science, EarlyView.This work demonstrates that weak‐drift slow carriers are preferentially captured at generic semiconductor surfaces/interfaces and recombine. This process is manipulated to achieve tailored spectral response. A tens of µm‐wide depletion region is created to observe surface collection rates for photocarriers generated at different positions.

Positron annihilation induced Auger electron spectroscopy [PDF]
AIP Conference Proceedings, 1991 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.

Studies of Composition of Surfaces and Interfaces with the Use of Auger Electron Spectroscopy [PDF]
, 1996 Processes leading to the Auger electron emission from the sample bombarded with a primary electron beam are discussed. It is shown that every element has its characteristic spectrum of Auger lines, and that owing to a small inelastic mean free path of ...
