Making the new silicon. Modern electronics are based on silicon. During the 20th century, this material enabled the development of computers, cell phones and modern communications. However, in spite of the tremendous impact that silicon has had in our lives, there are many things that silicon does not do well. For example, it does not emit light, which prevents its use in general illumination applications. At the same time, the maximum voltage it can handle quickly drops with operating frequency, which increases the size and reduces the performance of any electronics that requires high voltage, such as the electronics used in electric vehicles, inside laptop power adapters or to control the electric grid.
Gallium Nitride (GaN) is a revolutionary new semiconductor material with unique properties that is quickly changing our world. It can be found in cell phones, LED light bulbs and TV screens, thanks to its efficient light emission. In addition to the more than $15+ billion market in solid state lighting, GaN is also changing electronics and energy management, a $60+ billion market that will change forever how we use energy.
This sounds like a start-up we certainly need to follow!
