Abstract:
A light emitting element comprising:a p-n junction portion responsible for light emission formed between a p-type GaAs1-aPa layer (where a represents mixed crystal ratio and satisfies a relation of 0.45&lE;a&lE;1.0) and an n-type GaAs1âˆ’aPa layer (where a represents mixed crystal ratio and satisfies a relation of 0.45&lE;a&lE;1.0); and a first nitrogen-doped zone formed in a portion including the p-n junction interface between such p-type GaAs1-aPa layer and n-type GaAs1-aPa layer, wherein nitrogen concentration of such first nitrogen-doped zone is set higher than the nitrogen concentration whereat the emission luminance of the light emitting element reaches maximum.
