A team led by Haitao Wang and Jia Wang at the Institute of Materials and Systems for Sustainability (IMaSS), Nagoya University, has come up with a new way of lowering the resistance of p-type GaN contacts.

Researchers created an "electron lighthouse" using two lasers to steer electron beams in semiconductors without electricity. This quantum interference breakthrough could transform sensing, telecom & optoelectronics.

An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, their response is averaged over many different local environments and therefore appear isotropic, as expected for a cubic crystal. In contrast, the optical excitations, known as excitons, are much more sensitive to the local arrangement of atoms. Surpr

Researchers at Tohoku University have uncovered the long-standing mystery behind the synthesis of Janus two-dimensional (2D) semiconductors, paving the way for more precise manufacturing of materials used in future electronics and clean energy technologies. Janus 2D materials are named after the two-faced Roman god because their top and bottom surfaces are composed of different elements. This asymmetry creates a strong internal electric field, making them attractive for appl

Controlling heat flow is a major challenge for next-generation electronics and photonic devices. Now, an international team led by ICN2, UAB, TU/e, and McGill has discovered a completely new heat transport regime in ultrathin 2D semiconductors.

The latest study on an electron-on-neon qubit, invented at Argonne, shows its strong potential to scale quantum information processing.

Relaxor ferroelectrics have been used in electronics and sensors for decades, but the source of their unique properties was a mystery until now.

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

Findings reveal how molecular defects can enhance light conversion efficiency

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.

Air cavities help atom-thin semiconductors shine brighter

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
