Sound and light trapped by disorder

Sound and light are crucial for our life and are essential in many energy, communication and information technologies. Their interaction allows many fundamental observations in physics, from the detection of cosmic gravitational ...

When heat ceases to be a mystery, spintronics becomes more real

The development of spintronics depends on materials that guarantee control over the flow of magnetically polarized currents. However, it is hard to talk about control when the details of heat transport through the interfaces ...

Iron-rich lamellae in a semiconductor

There is often a pronounced symmetry when you look at the lattice of crystals: It doesn't matter where you look—the atoms are uniformly arranged in every direction. This behavior would also be expected of a crystal, which ...

Directivity to improve optical devices

A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...

Perovskites – materials of the future in optical communication

Researchers at the universities of Linköping and Shenzhen have shown how an inorganic perovskite can be made into a cheap and efficient photodetector that transfers both text and music. "It's a promising material for future ...

Extreme conditions in semiconductors

Scientists from the University of Konstanz and Paderborn University have succeeded in producing and demonstrating what is known as Wannier-Stark localization for the first time. In doing so, the physicists managed to overcome ...

Researchers boost performance quality of perovskites

Solar cells are devices that absorb photons from sunlight and convert their energy to move electrons—enabling the production of clean energy and providing a dependable route to help combat climate change. But most solar ...
