A new study led by the Aerospace Information Research Institute of the Chinese Academy of Sciences, along with their ...

High pressure has quietly become one of the most powerful tools in condensed matter physics, and a new result in ...

Chirality is a fundamental property of matter that determines many biological, chemical and physical phenomena. Chiral solids, for example, offer exciting opportunities for catalysis, sensing and ...

In analogy to the amplification of light in a laser, vibrations of a semiconductor crystal, so called phonons, were enhanced by interaction with an electron current. Excitation of a ...

Conventionally, active metasurface scientists have mainly concentrated on altering the dielectric constant and permeability of the substrate, which usually leads to resonance effect and ohmic loss.

To overcome global energy challenges and fight the looming environmental crisis, researchers around the world investigate new materials for converting sunlight into electricity. Some of the most ...

The properties of a GaSe crystal allow researchers to build a compact terahertz source with a tuning range in excess of 5 THz. Researchers in the US claim to have built a compact source of widely ...

Researchers build a terahertz radiation source based on a GaP crystal that has a tuning range of 2.5 THz. Scientists in Japan have used difference-frequency generation (DFG) to produce tunable, high ...

Today's autonomous vehicles rely on cameras, radar and LiDAR sensors to understand their surroundings and avoid obstacles on the road. Boston, Massachusetts-based startup Teradar believes it can beat ...

Terahertz light has the ability to control solids at the atomic level, forming chiral structures of left- and right-handedness. Chirality refers to objects that cannot be superimposed to their mirror ...
