The physics of GaN-based light-emitting diodes (opens in new tab)

The past three decades have witnessed substantial progress in the performance of GaN-based light-emitting diodes. GaN light-emitting diodes, combined with wavelength-converting materials, enable highly efficient white-light sources that have caused a revolution in lighting applications, reaching more than 50% market adoption in the USA. This Review article discusses the underlying physics of GaN-based light-emitting diodes, focusing on how the quantum efficiency of the active region is affect...
