Determining bismuth content in GaAsBi alloys by energy‐dispersive X‐ray spectroscopy: A case study with multiple sets of k*‐factors for analytical transmission electron microscopy

open access: yesJournal of Microscopy, EarlyView.
Abstract Measuring the bismuth (Bi) content of ternary gallium arsenide bismuthide (GaAsBi) alloys is important because it sensitively influences their bandgap, and Bi is known to segregate vertically to the surface and sometimes also laterally during growth, so elemental distribution maps need to be quantified.

Growth of ultimate high-density scintillating films for high-resolution X-ray imaging at synchrotrons

open access: yesOptical Materials: X
Scintillators are X-ray to visible light converters applied in X-ray imaging detectors used at synchrotrons. Drastically improved performances of the 4th generation synchrotron sources enable us to perform X-ray imaging experiments at higher energies ...

Diameter Dependence of Light Absorption in GaAs Nanowires Evidenced by Photoluminescence Spectroscopy

open access: yesAdvanced Optical Materials, Volume 14, Issue 5, 2 February 2026.
Photoluminescence spectroscopy is introduced as a qualitative method to probe light absorption in highly phase‐pure GaAs nanowire arrays and single nanowires, for which direct absorption measurements are challenging. Using defect‐line saturation and the exciton‐to‐plasma transition as indicators for the density of photogenerated charge carriers, a ...

d‐Wave Fermi Surface Instability in the Nematic Phase of Two Monolayer FeSe/SrTiO3

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
Angle‐resolved photoemission spectroscopy reveals a d‐wave nematic order in two‐monolayer FeSe/SrTiO3, showing degenerate dxz/dyz bands at Γ but a pronounced splitting at M. This momentum‐dependent anisotropy identifies the nematicity as a d‐wave Fermi surface (Pomeranchuk) instability, highlighting 2D FeSe as a model platform to explore the interplay ...

A Facile Route to Large‐Area 2D Pt

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
This work demonstrates a simple route to form continuous 2D platinum (Pt) films only up to 0.3 nm thick using a gallium oxide (GaOx) adhesion layer. The oxygen‐deficient GaOx reverses wetting thermodynamics, enabling scalable sputtering of transparent, conductive, and robust 2D Pt.
