Diffractive wavefront correction for Fe L‐edge spectroscopy on the meV scale

Journal of Synchrotron Radiation, Volume 33, Issue 4, Page 1085-1092, July 2026.
We propose an aberration‐corrected, wavelength‐dispersive instrument for soft X‐ray spectroscopy at an energy‐resolving power of (5–6) × 104, designed for, for example, resonant inelastic X‐ray scattering at synchrotron beamlines or X‐ray free‐electron lasers.We propose a wavelength‐dispersive instrument for high‐resolution soft X‐ray spectroscopy at ...

Atomic‐Scale Light Coupling Control in Ultrathin Photonic Membranes

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
Ultrathin photonic nanomembranes provide atomic‐scale control over the coupling between incident light and high‐Q photonic modes, enabling angstrom‐level resonance tuning and strong field confinement. When integrated with TMD monolayers, they further yield enhanced light–matter interactions, offering a versatile platform for advancing quantum photonics,

Large Transverse Thermoelectric Effect in Weyl Semimetal TaIrTe4 Engineered for Photodetection

Advanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
This experimental work shows that the anomalous scanning photocurrent response patterns of the Weyl semimetal TaIrTe4${\rm TaIrTe}_4$ under visible and long‐wave infrared illumination are due to a large transverse thermoelectric response of the material.

High‐Barrier Amorphous Al2O3 Film Deposited via Magnetic Field‐Confined for Ultrastable Hygroscopic Scintillators

SmartMat, Volume 7, Issue 3, June 2026.
The moisture‐induced degradation of hygroscopic scintillators limits their performance and lifespan in radiation detection. A 100 nm amorphous Al2O3 film, deposited at room temperature via FCVA with pulsed magnetic field confinement, offers high optical transmittance and ultralow moisture permeability.

Polarization-Independent Filter Based on 2-D Crossed Grating Under Oblique Incidence

IEEE Photonics Journal, 2018
The existing polarization-insensitive filters based on two dimensional (2-D) grating are mostly under normal incidence. However, in filtering optical devices, the normal incidence regime is usually avoided because it requires the use of beam separators ...
