Graphene and other carbon nanomaterials can replace scarce metals

Tue, 2017-09-19 18:40
Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become "conflict minerals" which can promote conflicts and oppression. New research shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene.

Optical, electrical bistability study sheds light on next-gen high speed data transfer

Tue, 2017-09-19 08:52
Today, electrical bistable devices are the foundation of digital electronics, serving as building blocks of switches, logic gates and memories in computer systems. However, the bandwidth of these electronic computers is limited by the signal delay of time constants important to electronic logic operations. In an attempt to mitigate these problems, scientists have considered the development of an optical digital computer, and one team has gone so far as to demonstrate the optical and electrical bistability for switching in a single transistor.

New quantum phenomena in graphene superlattices

Mon, 2017-09-18 22:06
Researchers have just shown the first new type of quantum oscillation to be reported for thirty years. It is the first of its kind to be present at high temperature and on the mesoscale and sheds light on the Hofstadter butterfly phenomenon.

Tiny electrically pumped micro-lasers epitaxially grown on industry standard silicon substrates

Mon, 2017-09-18 19:03
A group of researchers successfully demonstrated record-small electrically pumped micro-lasers epitaxially grown on industry standard (001) silicon substrates in a recent study. The thresholds and footprints are orders of magnitude smaller than those previously reported lasers epitaxially grown on Si.

World first: 'Storing lightning inside thunder'

Mon, 2017-09-18 18:37
In a world first, researchers have stored photonic information on a microchip as an acoustic wave. This allows precious extra time to store, process and then redistribute the data without relying on electronics, which produce excess heat. Such a hybrid chip could have a huge impact in cloud computing and telecommunication centers, which are overheating as we churn through data on our phones.

Sensing with a twist: A new kind of optical nanosensor uses torque for signal processing

Sat, 2017-09-16 17:31
As electronic devices get smaller, their ability to provide precise, chip-based sensing of dynamic physical properties such as motion become challenging to develop. An international group of researchers have put a literal twist on this challenge, demonstrating a new nanoscale optomechanical resonator that can detect torsional motion at near state-of-the-art sensitivity. Their resonator, into which they couple light, also demonstrates torsional frequency mixing, a novel ability to impact optical energies using mechanical motions.
