Defect Profiling of Oxide-Semiconductor Interfaces Using Low-Energy Muons
Muon spin rotation with low-energy muons (LE-μSR) is a powerful nuclear method where electrical and magnetic properties of surface-near regions and thin films can be studied on a length scale of ≈200 nm. This study shows the potential of utilizing low-energy muons for a depth-resolved characterization of oxide-semiconductor interfaces, i.e., for silicon (Si) and silicon carbide (4H-SiC). The performance of semiconductor devices relies heavily on the quality of the oxide-semiconductor interface; thus, investigation of defects present in this region is crucial to improve the technology.

Bright white coloring of Pacific cleaner shrimp revelead
In a study published in Nature Photonics, researchers at the Ben-Gurion University of the Negev, Israel, explain the bright, white-colored stripes from Pacific cleaner shrimps, one of the most efficient white reflectors found in nature.
Progress of the X06DA-PXIII beamline upgrade: First light in the optics hutch
On June 7, 2023, the PXIII project team successfully shone the first light into the optics hutch at the upgraded X06DA-PXIII beamline. It is an essential first step for testing new hardware and software solutions that will be implemented at SLS2.0.
Tender X-rays show how one of nature’s strongest bonds breaks
Short flashes of an unusual kind of X-ray light at SwissFEL and SLS bring scientists closer to developing better catalysts to transform the greenhouse gas methane into a less harmful chemical.
Tuning magnetoelectricity in a mixed-anisotropy antiferromagnet
Control of magnetization and electric polarization is attractive in relation to tailoring materials for data storage and devices such as sensors or antennae. In magnetoelectric materials, these degrees of freedom are closely coupled, allowing polarization to be controlled by a magnetic field, and magnetization by an electric field, but the magnitude of the effect remains a challenge in the case of single-phase magnetoelectrics for applications.
