Understanding high efficiency of deep ultraviolet LEDs

Friday, February 22, 2019 - 11:20 in Physics & Chemistry

Deep ultraviolet light-emitting diodes (DUV-LEDs) made from aluminium gallium nitride (AlGaN) efficiently transfer electrical energy to optical energy due to the growth of one of its bottom layers in a step-like fashion. This finding can lead to the development of even more efficient LEDs.
