The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study from ...

Light-emitting diodes (LEDs) are everywhere in modern life, from smartphones to home lighting. But today's LEDs have a major limitation: when you try to make them brighter by increasing their power, ...

LEDs with low polarization in a direction similar to standard LEDs show greater efficiency at higher power by resisting 'efficiency droop', a new study shows. The findings open the door to a new ...

Energy-efficient LED bulbs are becoming more and more popular each day. They use light-emitting diodes (LEDs) to produce light. Compared to traditional incandescent bulbs, LED bulbs use less energy, ...

In the coming year, industrial manufacturers will face a cacophony of pressures that threaten their profitability, viability, and even their very existence. Many manufacturers have discovered over the ...

Semiconductor lighting technology is developing rapidly. While seeking high luminous efficiency, low cost, and superior reliability, researchers are increasingly focusing on the effects of LED ...

Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. The materials physics shows that this is possible, the same semiconductor ...
