Terahertz

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 promising candidates for high-efficiency…

An international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has developed a new method for the efficient coupling of terahertz waves with much shorter wavelengths, so-called spin waves. As the experts report in the…

Researchers have developed a neural network model that uses terahertz time-domain spectroscopy (THz-TDS) data for non-invasive burn assessment. They combined the new approach with a handheld imaging device that they developed specifically…

A class of nonvolatile memory devices, called MRAM, based on quantum magnetic materials, can offer a thousandfold performance beyond current state-of-the-art memory devices. The materials known as antiferromagnets were previously…

In a multidisciplinary project, researchers at the Georgia Institute of Technology and Georgia Tech-Lorraine used terahertz imaging and signal processing techniques to look beneath the corroded surface of a 16th-century lead funerary cross.…

It's not easy to be sure that drugs and supplements with twisted -- or chiral -- structures are turning in the correct direction. Now, twirling infrared light can probe both the structures of molecular crystals and their twists, research…

Many semiconducting materials are possible candidates for solar cells. In recent years, perovskite semiconductors in particular have attracted attention, as they are both inexpensive and easy to process and enable high efficiencies. Now a…

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…

Terahertz radiation has a wavelength of typically a little less than one millimetre -- a technically difficult range. Electromagnetic waves with longer wavelengths can be generated with ordinary electronic components (such as transistors)…

They are regarded as one of the most interesting materials for future electronics: Topological insulators conduct electricity in a special way and hold the promise of novel circuits and faster mobile communications. Under the leadership of…
