LIGHT-EMITTING DEVICE

摘要

A light-emitting device having an active layer made of a nitride semiconductor containing In, especially a light-emitting device emitting a light of long wavelength (above 550 nm) and having an improved output power, wherein the active layer is formed between an n-type semiconductor layer and a p-type semiconductor layer and includes a well layer made of Inx1Ga1-x1N (x1>0) containing In and a first barrier layer formed on the well layer and made of Aly2Ga1-y2N (y2>0) containing Al.
