TRANSICIONES AUGER RADIATIVAS RESONANTES KLM EN Cu

open access: yesAnales (Asociación Física Argentina), 2013
Se llevaron a cabo estudios de alta resolución de procesos de dispersión inelástica 1s2pj (j = 1/2, 3/2) en el régimenresonante (RIXS) en Cu. Además de los espectros RIXS, se observaron contribuciones de nuevos canales dedesexcitación, los cuales fueron ...

Electronic Correlation Effects in the Response of Graphene and MoS2 Monolayers to the Impact of Highly‐Charged Ions

open access: yesphysica status solidi (b), EarlyView.
The response of graphene and MoS2 monolayers to highly‐charged impinging ions is investigated using nonequilibrium Green functions theory. Electronic correlations are found to have a significantly stronger influence on the ultrafast ion‐induced electron dynamics in MoS2 than in graphene.

Auger Parameter Analysis for TiN and AlN Thin Films via Combined In Situ XPS and HAXPES

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT Auger parameter analysis provides in‐depth information about electronic and chemical bonding properties of TiN and AlN thin films, which are relevant across a wide range of technologies. Meaningful interpretation and analysis of Auger parameter of these materials have been hindered due to, among other reasons, the absence of reliable ...

Quantitative Model of Internal Analyzer Scattering in a Hemispherical Electron Analyzer and Its Application to Improve the Accuracy of the Transmission Function

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT Internal scattering within hemispherical electron analyzers (HEA) is common when operating at low pass energies, where the instrument resolution of X‐ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy experiments are at their best.

Unraveling Interband Hot‐Electron Transfer in Hydrogenated Au@Cu2O/TiO2 Heterostructure Nanocrystals for Enhanced Hydrogen Evolution

open access: yesSmall, EarlyView.
Hydrogenated Au@Cu2O/TiO2 nanocrystals with oxygen‐vacancy‐engineered heterostructures enable efficient hot‐electron transfer. A Z‐scheme heterojunction forms between TiO2 and Cu2O, suppressing electron‐hole recombination and leading to a hydrogen evolution rate of 9.3 mmol g−1 h−1, with AQYs of 2.5% at 650 nm and 0.8 % at 800 nm, extending activity ...

Standardized Elemental Composition Analysis of Graphene‐Related 2D Materials (GR2M) With SEM/EDS and XPS Works Reliably

open access: yesSmall, EarlyView.
The elemental composition of a series of laboratory graphene oxide and reduced graphene oxide materials and a commercial graphene oxide material of high quality is analyzed with the standardless SEM/EDS quantification. XPS is used as a reference method.

Quantifying the Spatial Distribution of Series Resistance in Monolithic Perovskite/Silicon Tandem Solar Cells Using Voltage‐Dependent Photoluminescence Imaging

open access: yesSmall, EarlyView.
Spatially resolved series resistance in monolithic perovskite/silicon tandem solar cells is extracted using voltage‐dependent photoluminescence imaging. The method is robust against current mismatch, shunt resistance, and luminescence coupling. Even in a high‐performance 29% efficiency device, resistive losses contribute up to 1.9% absolute efficiency ...

Multichannel Photoluminescence of Graphene Quantum Dots Across Femtosecond to Cryogenic Timescales

open access: yesSmall, EarlyView.
This study reveals how graphene quantum dots emit light across all relevant timescales, from femtoseconds to cryogenic steady states. By integrating optical Kerr gating, time‐correlated single‐photon counting, and low‐temperature photoluminescence, distinct intrinsic, surface, and defect‐related emission channels are temporally and spectrally ...
