Two-dimensional material shows promise for optoelectronics

A team of MIT researchers has used a novel material that’s just a few atoms thick to create devices that can harness or emit...

Smartphones become ‘eye-phones’ with low-cost devices

Researchers at the Stanford University School of Medicine have developed two inexpensive adapters that enable a smartphone to capture high-quality images of the front...

Micro-LEDs shed light on brain disorders

To better understand and one day provide improved treatments for depression, addiction and anxiety, researchers at Washington University School of Medicine in St. Louis...

Wagon-Wheel Pasta Shape for Better LED

One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized...

Bright, laser-based lighting devices

As a modern culture, we crave artificial white lights -- the brighter the better, and ideally using less energy than ever before. To meet...

Toward a truly white organic LED

By inserting platinum atoms into an organic semiconductor, University of Utah physicists were able to "tune" the plastic-like polymer to emit light of different...

Wireless devices go battery-free with new communication technique

We might be one step closer to an Internet-of-things reality. University of Washington engineers have created a new wireless communication system that allows devices to...

Nanosensor turns pressure into light

Researchers at the Georgia Institute of Technology want to put your signature up in lights – tiny lights, that is. Using thousands of nanometer-scale...

Beyond silicon: Transistors without semi-conductors

For decades, electronic devices have been getting smaller, and smaller, and smaller. It's now possible—even routine—to place millions of transistors on a single silicon...
