摘要:
The nitride semi-conductive light emitting layer in this invention comprises a single crystal substrate 1 for epitaxial growth, a first buffer layer 2, an n-type nitride semi-conductive layer 3, a second buffer layer 4, a third buffer layer 5, a light emitting layer 6 , and a p-type nitride semi-conductive layer 7. The first buffer layer 2 is laminated to a top side of the single crystal substrate 1 . The n-type nitride semi-conductive layer 3 is laminated to a top side of the first buffer layer 2. The third buffer layer 5 is laminated to a top side of the n-type nitride semi-conductive layer 3 with the second buffer layer 4 being interposed therebetween. The light emitting layer 6 is laminated to a top side of the third buffer layer 5. The p-type nitride semi-conductive layer 7 is laminated to a top side of the light emitting layer 6. The third buffer layer 5 serves as a planarized base for growth of the light emitting layer 6 so as to reduce a threading dislocation and a residual distortion in the light emitting layer 6 . This nitride semi-conductive light emitting device reduces a piezoelectric field in the light emitting layer by exploiting carriers generated in the third buffer layer 5. The third buffer layer 5 is doped with an Si impurity serving as a donor.
