Terahertz light holds enormous potential for tomorrow's technologies. It might succeed 5G by enabling extremely fast mobile communications connections and wireless networks. The bottleneck in the transition from gigahertz to terahertz frequencies has been caused by insufficiently efficient sources and converters. A research team with the participation of HZDR has now developed a material system to generate terahertz pulses much more effectively than before. It is based on graphene, coated with a metallic lamellar structure.
Researchers at Drexel University's College of Engineering have reported that fabric coated with a conductive, two-dimensional material called MXene, is highly effective at blocking electromagnetic waves and potentially harmful radiation. The discovery is a key development for efforts to weave technological capabilities into clothing and accessories.
University at Buffalo researchers report a new, two-dimensional transistor made of graphene and molybdenum disulfide that needs less voltage and can handle more current than today's semiconductors.

The quest to discover pioneering new ways in which to manipulate how light travels through electromagnetic materials has taken a new, unusual twist.
Researchers have developed the first technology capable of sending digital information, such as a photo or password, by touching a surface with your finger.
Researchers have developed new 3D-printed microlenses with adjustable refractive indices - a property that gives them highly specialized light-focusing abilities. This advancement is poised to improve imaging, computing and communications by significantly increasing the data-routing capability of computer chips and other optical systems, the researchers said.
In collaboration with the Technical University of Denmark (DTU), the Department of Engineering at Aarhus University has developed photonic sensor technology that can pave the way for a portable, reliable and, above all, inexpensive device for detecting ammonia and other gases in agriculture. The new technology has been developed as part of the Ecometa project, which has received DKK 12.5 million funding from Innovation Fund Denmark.
New antennas so thin that they can be sprayed into place are also robust enough to provide a strong signal at bandwidths that will be used by fifth-generation (5G) mobile devices. Performance results for the antennas, which are made from a new type of two-dimensional material called MXene, were recently reported by researchers at Drexel University and could have rammifications for mobile, wearable and connected "internet of things" technology.
Scientists of Far Eastern Federal University (FEFU) with international collaborators propose direct magnetic writing of skyrmions, i.e. magnetic quasiparticles, and skyrmion lattices, within which it is possible to encode, transmit, process information, and produce topological patterns with a resolution of less than 100 nanometers. This brings closer miniaturized post-silicon electronics, new topological cryptography techniques, and green data centers, reducing the load on the Earth's ecosystem significantly.
