Patent abstract
A deep ultraviolet LED with a design wavelength of λ is provided that includes a reflecting electrode layer, a metal layer, a p-type GaN contact layer, and a p-type AlGaN layer that are sequentially stacked from a side opposite to a substrate, the p-type AlGaN layer being transparent to light with the wavelength of λ; and a photonic crystal periodic structure that penetrates at least the p-type GaN contact layer and the p-type AlGaN layer. The photonic crystal periodic structure has a photonic band gap.
