Abstract
A light emitting device includes: a plurality of n-type III-V group compound semiconductor layers; a plurality of p-type III-V group compound semiconductor layers; and an active layer. Carbon atoms and II-group element atoms are both added to at least one of the plurality of p-type III-V group compound semiconductor layers. Alternatively, carbon atoms and Si atoms are both added to at least one of the plurality of n-type III-V group compound semiconductor layers. Another semiconductor light emitting device has a current blocking structure formed on the double hetero (DH) junction structure, and the current blocking structure at least includes a two-layered n-type current blocking layers including a Se-doped n-type first current blocking layer provided closer to the DH junction structure and a Si-doped n-type second current blocking layer formed on the n-type first current blocking layer.
