Spintronics: How an atom-thin insulator helps transport spins

An intermediate layer consisting of a few atoms is helping to improve the transport of spin currents from one material to another. Until now, this process involves significant losses. A team from Martin Luther University ...

New compact terahertz laser with 120 frequencies

Researchers have taken a major step towards bringing terahertz frequencies out of their hard-to-reach region of the electromagnetic spectrum and into everyday applications. In a new paper, the researchers demonstrate a first-of-its-kind ...

Quantum material to boost terahertz frequencies

Topological insulators conduct electricity in a special way and hold the promise of novel circuits and faster mobile communications. Under the leadership of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a research team ...

Unique terahertz microscope can be operated remotely

With a wave length of about half a millimeter, terahertz radiation fills the gap between visible light and radio waves. This radiation lends itself very well to the in-depth measurement of the electrical properties of new ...
