Abstract
A light emitting diode (LED) comprises: an n-doped portion; a p-doped portion; and a light emitting region located between the n-doped portion and the p-doped portion. The light emitting region comprises: a light-emitting layer which emits light at a peak wavelength between 400 and 599 nm under electrical bias thereacross; a III-nitride layer located on the light-emitting layer; and a III-nitride barrier layer located on the III-nitride layer. The light emitting diode comprises a porous region of III-nitride material. An LED array and a method of manufacturing an LED with a peak emission wavelength between 400 nm and 599 nm under electrical bias are also provided.
