Group III nitride semiconductor device and light-emitting device using the same |
| abstract |
An object of the present invention is to provide a Group III nitride semiconductor device exhibiting improved crystallinity and a good performance. The inventive Group III nitride semiconductor device comprises a substrate, and a plurality of Group III nitride semiconductor layers provided on the substrate, wherein a first layer which is in contact with the substrate is composed of silicon-doped AlxGa1-xN (0≦x≦1). Also, the inventive Group III nitride semiconductor device comprises a substrate, and a plurality of Group III nitride semiconductor layers provided on the substrate, wherein a first layer which is in contact with the substrate is composed of AlxGa1-xN (0≦x≦1), and the difference in height between a protrusion and a depression which are present at the interface between the first layer and a second layer provided thereon is 10 nm or more and is equal to, or less than, 99% the thickness of the first layer. |
