Researchers have achieved a tiny high-power narrow-beam laser that operates in the terahertz frequencies. The new devices are the first terahertz laser devices to reach three key performance goals at once - high power, tight beam, and broad frequency tuning - in a design that can work outside a laboratory.

Researchers have discovered a way to make self-assembled nanowires of transition metal chalcogenides at scale using chemical vapor deposition. By changing the substrate where the wires form, they can tune how these wires are arranged, from aligned configurations of atomically thin sheets to random networks of bundles.
