New research explores graphene-silicon devices for photonics applications. If you use a smartphone, laptop, or tablet, then you benefit from research in photonics, the study of light. At the University of Delaware, a team led by Tingyi Gu, an assistant professor of electrical and computer engineering, is developing cutting-edge technology for photonics devices that could enable faster communications between devices and thus, the people who use them.

The research group recently engineered a silicon-graphene device that can transmit radiofrequency waves in less than a picoseco...

‘Hybrid’ cathodes could provide more power for a given weight and volume. Researchers around the globe have been on a quest for batteries that pack a punch but are smaller and lighter than today’s versions, potentially enabling electric cars to travel further or portable electronics to run for longer without recharging. Now, researchers at MIT and in China say they’ve made a major advance in this area, with a new version of a key component for lithium batteries, the cathode.

The team describes their concept as a “hybrid” cathode, because it combines aspects of two different approaches that have b...

Due to its potential to make computers faster and smartphones more efficient, spintronics is considered a promising concept for the future of electronics. In a collaboration including the Max Planck Institute for Intelligent Systems (MPI-IS) and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a team of researchers has now successfully generated so-called spin waves much more easily and efficiently than was previously deemed possible...

Smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. This problem has now been overcome by a KAIST research team, who developed a textile-based wearable display module technology that is washable and does not require an external power source.

To ease out the problem of external power sources and enhance the practicability of wearable displays, Professor Kyung Cheol Choi from the School of Electrical Engineering and his team fabricated their wearing display modules on real textiles that integrated polymer solar cells (PSCs) with organic light emitting diodes (OLEDs).

PSCs have been one of the most promising candidates for a next-generation...
