2D materials are widely seen as a promising path toward better computer chips. Researchers at TU Wien now show: some of these materials are unsuitable due to an underestimated effect. But there are alternatives

A Würzburg research team has achieved the world’s first experimental confirmation of the Kardar–Parisi–Zhang (KPZ) universality class in two-dimensional quantum systems. Using polaritons in a precisely engineered GaAs semiconductor cooled to near absolute zero, they tracked the nonlinear, random growth process in both space and time—proving the famous 1986 growth equation holds in 2D.

Hair-width LEDs could replace lasers — and a UCSB doctoral student is helping make it happen

A monolayer of the transition metal dichalcogenide alloy MoWSe₂ with K⁺ and K⁻ valleys. The purple lines indicate the external magnetic field, the application of which leads to the splitting of exciton state energies as a result of the Zeeman effect. This phenomenon is illustrated as different separations between the valence band and the conduction band in the two valleys. @ Grzegorz Krasucki, Faculty of Physics, University of Warsaw Scientists from the Faculty of Physics at

The team developed a platform that uses powerful X-rays from the lab’s LCLS X-ray laser to resolve for the first time the evolution of instabilities in high-density plasmas.

Clusters of 10 tantalum atoms, arranged in triangles, create stress in the crystal’s structure. This stress unlocks unique magnetic properties, essential for future technologies such as quantum computing.
