Terahertz technology escapes the cold

Terahertz (THz) radiation is a bit like a treasure chest that resists being opened fully. Residing in the electromagnetic spectrum between the infrared and microwave regions, THz radiation combines a range of properties that ...

Terahertz spectroscopy enters the single-molecule regime

The interaction of light with matter is the basis of spectroscopy, a set of techniques lying at the heart of physics and chemistry. From infrared light to X-rays, a broad sweep of wavelengths is used to stimulate vibrations, ...

Radiation technique could offer less harmful alternative to X-rays

A new source of intense terahertz (THz) radiation, which could offer a less harmful alternative to X-rays and has strong potential for use in industry, is being developed by scientists at the University of Strathclyde and ...

Microanalysis of biological samples for early disease detection

The use of terahertz (THz) waves for biosensing is currently receiving considerable attention. THz waves are able to detect molecular vibrations and rotations, without using labels that can affect the properties of the substances ...

On-chip observation of THz graphene plasmons

Researchers developed a technique for imaging THz photocurrents with nanoscale resolution, and applied it to visualize strongly compressed THz waves (plasmons) in a graphene photodetector. The extremely short wavelengths ...
