Researchers from Sweden, Finland and Japan have now constructed a semiconductor component in which information can be efficiently exchanged between electron spin and light – at room temperature and above. Semiconductor spintronics have potential for opto-spintronics, which will allow integration of spin-based information processing/storage with photon-based information transfer/communications. Unfortunately, progress has so far been severely …
Today’s information technology relies on electronics that consumes a huge amount of energy, the electrons within electric currents can also transfer a form of angular momentum called spin. ‘Spin-based electronics or ‘spintronics’, that exploits spin current, has the potential to be not just significantly faster, but also more energy-efficient. Scientists have recently discovered that some …
Buckminsterfullerene, C60, is now the largest molecule that has ever been analyzed for quantum vibrations. Fully understanding and controlling the quantum details of buckyballs could lead to quantum computers using molecules. Buckyballs could act like a pristine network of 60 atoms. The core of each atom would have an identical nuclear spin. Each spin would …
A researcher with the Erik Jonsson School of Engineering and Computer Science at UT Dallas has designed a novel computing system made solely from carbon that might one day replace the silicon transistors that power today’s electronic devices. “The concept brings together an assortment of existing nanoscale technologies and combines them in a new way,” …
A new class of “miracle materials” called organic-inorganic hybrid perovskites could be a game changer for future spintronic devices. Researchers discovered that the perovskites possess two contradictory properties necessary to make spintronic devices work—the electrons’ spin can be easily controlled, and can also maintain the spin direction long enough to transport information, a property known …
With an increased interest in spin logic devices compatible with the existing semiconductor technology, manipulating electron spins in nonmagnetic semiconductors has been one of the most active research directions in spintronics, promising smaller, faster, less power-consuming information-processing and communication devices. However, several technical challenges have to be overcome in semiconductor spintronics, such as efficient spin …
Featuring low heat dissipation, devices based on spin-wave logic gates promise to comply with increasing future requirements in information processing. In this work, we present the experimental present Researchers have created an experimental realization of a majority gate based on the interference of spin waves in an Yttrium-Iron-Garnet-based waveguiding structure. This logic device features a …
IBM predicts five innovations for the next five years In five years AI for diagnosing mental health Cognitive computers will analyze a patient’s speech or written words to look for tell-tale indicators found in language, including meaning, syntax and intonation. Combining the results of these measurements with those from wearables devices and imaging systems (MRIs …
China flew an improved version of its Shenyang FC-31 Gyrfalcon stealth fighter. Compared to the previous prototype, the new version features a host of refinements and has started to resemble a genuine fifth-generation stealth aircraft in many ways. The FC-31 is intended for military export markets. It is expected to be priced around $70 million. …
India previously had a ‘finalised’ agreement to buy 126 Rafale aircraft at a total cost of US$10.2 billion but this cut down to 36 aircraft at a cost of US$8.7 billion. So India is getting 30% of the original order for 80% of the cost. Three squadrons were phased out in January 2016, the IAF …
NanoSteel®, a leader in nanostructured steel materials, and the company’s joint development launch partner, AK Steel Corporation, have won the Platts Global Metals “Breakthrough Solution of the Year” Award. The Platts Global Metals Award recognizes the product’s groundbreaking properties, which offer the combination of both high strength (1200 MPa) and high formability (50% elongation), exceeding …
