Probing carrier dynamics in photo-excited graphene with time-resolved ARPES

, 2016
The dynamics of photo-generated electron-hole pairs in solids are dictated by many-body interactions such as electron-electron and electron-phonon scattering.

Interplay Between Structure and Interfacial Interactions in Fe‐Gd Synthetic Ferrimagnets

Advanced Electronic Materials, EarlyView.
Synthetic ferrimagnets with nearly identical Gd–Fe compositions but different architectures and crystallinity were investigated by element‐resolved microscopy, structural analysis and atomistic spin simulations. The results show that Curie temperature and domain evolution are governed primarily by structural order and interface quality, demonstrating ...

Precise Tailoring of Charge Transport Characteristics in Zr and Hf Doped Indium Tin Oxide Thin Film Transistors

Advanced Electronic Materials, EarlyView.
Zirconium, hafnium, and mixed zirconium/hafnium doped indium tin oxide thin films are accessible by atomic layer deposition. The amorphous functional films are about 8 nm thick and show a high interdiffusion of all elements. Their transistor characteristics can be modulated depending on the amount of Zr and Hf oxide phases incorporated in these thin ...

Shedding Light on Common Misinterpretations in Photocatalyst Characterization

Advanced Energy Materials, EarlyView.
For heterogeneous semiconductor‐based photocatalysts, Marschall et al. highlight common misconceptions in material synthesis, characterization, and performance evaluation, together with detailed explanations on how to avoid them. The guidelines thus presented can help to improve reporting of photocatalyst performance in environmental applications, such

Topographic compensation in auger electron spectroscopy.

Hyomen Kagaku, 1987
Abstract The scanning Auger microprobe (SAM) produces Auger images which provide information on the elemental distribution of specimen surfaces. However specimen topography affects the data obtained. To eliminate the topographical effect, the peak‐to‐background ratio, ( P −

Decoding Gas Evolution Pathways and Interfacial Chemistry in Layered Oxide Cathodes for Safer Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Gas evolution behaviors of sodium layered oxide cathodes with varying compositions, cutoff voltages, dopants, and particle sizes/morphologies have been systematically investigated by online electrochemical mass spectrometry. The fundamental outgassing mechanisms of sodium‐based cathodes compared to lithium‐based cathodes have been elucidated.

Electric‐Field‐Driven Bilayer Interphase from Oxygenated Nanodiamond‐Carbon Nanoparticles for Dendrite‐Free Lithium Metal Batteries

Advanced Energy Materials, EarlyView.
Electric‐field‐driven carbon migration within an oxygen‐functionalized nanodiamond/carbon composite induces the formation of a vertically graded interphase that homogenizes Li‐ion flux and suppresses dendritic nucleation. This hierarchically organized structure stabilizes the electrode–electrolyte interface and delivers durable, dendrite‐free operation

Covariance mapping of two-photon double core hole states in C2H2 and C2H6 produced by an x-ray free electron laser

New Journal of Physics, 2015
Few-photon ionization and relaxation processes in acetylene (C _2 H _2 ) and ethane (C _2 H _6 ) were investigated at the linac coherent light source x-ray free electron laser (FEL) at SLAC, Stanford using a highly efficient multi-particle correlation ...
