Abstract:
1. A semiconductor light emitting device including: an active layer made of a first nitride III-V compound semiconductor containing In and Ga; an intermediate layer in contact with the active layer and made of a second nitride III-V compound semiconductor containing In and Ga and different from the first nitride III-V compound semiconductor; a cap layer in contact with the intermediate layer and made of a third nitride III-V compound semiconductor containing Al and Ga; an optical guide layer in contact with the cap layer and made of a sixth nitride III-V compound semiconductor containing Ga; and a p-type clad layer in contact with the cap layer and made of a seventh nitride III-V compound semiconductor containing Al and Ga and different from the third nitride III-V compound semiconductor, wherein, the active layer, the intermediate layer, the cap layer and the optical guide layer are grown in a carrier gas atmosphere containing substantially no hydrogen and containing nitrogen as the major component thereof; and the p-type clad layer are grown in a carrier gas atmosphere containing nitrogen and hydrogen as major components thereof.
