Abstract(in English) | Ultraviolet Light Emitting Diodes (UV-LEDs) are promising for various applications such as photocatalyst or excitation source for white LEDs. In this paper, we report on high-brightness UV-LEDs on Si substrate aiming at the low cost fabrication. InAlGaN quaternary alloy with high In content is used in the active layer in which localized excitons screen the effect of the non-radiative recombination center caused by the dislocations. The InAlGaN multi-quantum-well active layers exhibit very high internal quantum efficiency of 15% at around 350nm which is as comparable high as that on SiC for the UV-emission. |
