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 has ...

Gallium nitride (GaN) and its wide bandgap cousin silicon carbide (SiC) have started to disrupt power electronics. Ironically, ... Blue LED pioneers Akasaki, Amano, and Nakamura won the 2014 Nobel ...

A blue LED held up by its inventor, [Shuji Nakamura]. By the time that ... also sought to investigate gallium nitride crystal-based blue LEDs rather than the much more promising zinc-selenium, ...

This was when a young engineer called Herbert Maruska had the idea that a substance called gallium-nitride (GaN) would be perfect for a blue LED. After much tinkering, he successfully created the ...

Thanks to the use of the material gallium nitride, which produces blue light, LEDs use roughly 75% less electricity and last 25 times longer than previous forms of lighting. Image by Bill Bradford ...

Gallium Nitride (GaN) isn’t new to the scene. It burst onto the tech world in the 90s, revolutionizing semiconductors through the creation of the first white LEDs, blue lasers, and vibrant full ...

MIT researchers have developed a clever new way to make computer chips faster, more energy-efficient, and cheaper—by using ...

The advanced semiconductor material gallium nitride will likely be key for the next generation of high-speed communication ...
