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 ...

NREL test helps make moisture barriers better

Moisture—in the form of humidity, water spills, or rainfall—spells early demise for cell phones, light-emitting diode (LED) displays, TVs, and solar photovoltaic (PV) panels worldwide.

Laser diodes versus LEDs

Solid-state lighting based on light-emitting diodes (LEDs) is the most efficient source of high color quality white light. Nevertheless, they show significant performance limitations such as the "efficiency droop". Blue laser ...
