Articles about 'gallium nitride'

Today, the Nobel Prize for Physics 2014 has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for their invention of a new energy-efficient and environment-friendly light source – the blue light-emitting diode (LED). University of Cambridge researchers are building on their work to produce more cost-effective gallium nitride LEDs that can have widespread use in homes and offices.

Gallium nitride has been described as “the most important semiconductor since silicon” and is used in energy-saving LED lighting. A new £1million growth facility will allow Cambridge researchers to further reduce the cost and improve the efficiency of LEDs, with potentially huge cost-saving implications.

A remarkable light-emitting material, gallium nitride, could slash electricity consumption, purify water and kill superbugs.
