The Leeds team has secured a new grant of £2 million from the Engineering and Physical Sciences Research Council (EPSRC) to shed light on the changes in behaviour and properties of nano-scale systems within the least explored area of the electromagnetic spectrum, the terahertz region.
The combined expertise at Leeds will fuse two fundamental areas of science – nanoscience, which focuses on decreasing size, and high frequency science, which focuses on high speed electronics.
Project leader Dr John Cunningham of the School of Electronic and Electrical Engineering explains: “The dimensions of electronic devices have reduced so much that they can be literally a few atoms in size – but at this scale, they exhibit different properties than their larger scale counterparts. These properties can be directly revealed or even changed using radiation from the terahertz region of the spectrum. If we want to continue to provide ever-smaller electronic systems that work at ever-faster speeds, we must find new ways of enabling this development by understanding exactly how they work. It’s an exciting project for us because we’re bringing together two areas of fundamental science that have rarely been studied together.”
Technologies using the radiation from many regions of the electromagnetic spectrum are well developed: the use of radio waves, x-rays and microwaves are now second nature in modern life. But the terahertz region, often called the ‘Terahertz gap’ because of the lack of commercially available sources and detectors for this region, is considered to be the ‘final frontier’ in understanding the electromagnetic spectrum. The Leeds team believes that its unique properties could offer the gateway to the next generation of new nano-electronics.
Terahertz radiation is found in the electromagnetic spectrum between the microwave region (where satellite dishes and mobile phones work) and infra-red light, but ways to generate detect and analyse terahertz radiation are not as advanced as other imaging techniques.
The four-year project will develop new methods to examine and assess nanoscale electronic systems using terahertz radiation, Future applications may include the development of new nano-scale high-frequency electronic devices in areas such as sensing, imaging and spectroscopy, and ultimately in communications.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
