Abstract:
1. A semiconductor light emitting device comprising: a substrate; an n-type semiconductor layer disposed over the substrate; a light emitting layer disposed over the n-type semiconductor layer and having a multiple quantum well (MQW) structure; the MQW structure having a plurality of well layers and barrier layers stacked alternately; one of the well layers being disposed between two of the barrier layers; a stress control layer disposed over the light emitting layer and made from Al a p-type carrier blocking layer disposed over the stress control layer and made from Al a p-type semiconductor layer disposed over the p-type carrier blocking layer; a n-type electrode disposed on and in ohmic contact with the n-type semiconductor layer; and a p-type electrode disposed at and in ohmic contact with the p-type semiconductor layer.
