Let There Be Light—With Gallium Nitride: The 2014 Nobel Prize in Physics
Graphical Abstract
Significant gains in energy savings now underway can be traced to a single invention—the blue light-emitting diode. GaN-based blue LED technology not only resulted in efficient white light sources, but continues to enable a host of applications and scientific inquiries. The researchers primarily responsible for the development of the blue LED were awarded the 2014 Nobel Prize in Physics.
