Japan's digital eyes show your emotions for you

Can't be bothered to show anyone what you're thinking? Then a Japanese scientist has the answer—a pair of digital eyes that can express delight and anger, or even feign boredom.

New technique makes LEDs brighter, more resilient

Researchers from North Carolina State University have developed a new processing technique that makes light emitting diodes (LEDs) brighter and more resilient by coating the semiconductor material gallium nitride (GaN) with ...

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 light. This proof-of-concept could lead to ultrathin, lightweight, and flexible photovoltaic cells, ...

Researchers develop first single-molecule LED

The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: a team led by the Institut de Physique et de Chimie des Matériaux de Strasbourg has developed the first ever single-molecule ...

Probing the inner secrets of nanowires

(Phys.org) —Semiconductor nanowires (NWs) are vanishingly small: NWs from a recent batch made by scientists in PML's Quantum Electronics and Photonics Division measure about 200 nanometers in diameter (less than 1/500th ...
