Carrier Diffusion Links Single Crystal Quality and Photoluminescence in Halide Perovskite Radiation Detectors

open access: yesAdvanced Materials, EarlyView.
By tracking bulk carrier diffusion both vertically and laterally, this study links photoluminescence behavior to crystal quality in CsPbBr3 γ‐ray detectors. Vertical diffusion governs spectral redshift, with high‐quality crystals exhibiting superior transport, while two‐photon microscopy reveals microscale defects that hinder diffusion in low‐quality ...

Exploring the interaction between ambient air pollution and road traffic noise on stroke incidence in ten Nordic cohorts

open access: yesEnvironment International
Introduction: Ambient air pollution and road traffic noise are stroke risk factors, but evidence on their potential joint effects remains limited. This study investigated the independent and joint associations of air pollution and road traffic noise on ...

Characterizing Emerging Detector Materials for Low‐Dose X‐Ray Imaging

open access: yesAdvanced Materials, EarlyView.
X‐ray medical imaging requires detectors that deliver images at as low as reasonably possible dose. This perspective outlines a universal characterization framework of X‐ray imaging detectors, suitable for both emerging semiconductor and scintillator materials, introduces a novel unified figure of merit that links dose with resolution, and offers an ...

Band Offsets from Angle‐Resolved Valence Band Photoemission Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Soft X‐ray Angle‐Resolved Photoemission Spectroscopy (SX‐ARPES) is employed to quantify conduction band offsets at semiconductor surfaces and interfaces by fitting valence band photoemission spectra. This method surpasses traditional techniques, providing accurate results for InAs and InSb systems.
