ABSTRACT:
A green light emitting device, includes an n-type gallium phosphide (GaP) substrate, an n-type GaP layer and a p-type GaP layer laminated on the n-type GaP substrate. The net donor concentration in the n-type GaP layer decreases abruptly in steps from the GaP substrate side to the p-type GaP layer side. Nitrogen is contained in only the n-type GaP layer portion closest to the p-type GaP layer.
