发明名称 Light-emitting device with double intermediate layers between mesa stripe and iron-doped current blocking layer
摘要 A light-emitting device that reduces the leak current flowing along the sides of the mesa stripe is disclosed. The device provides the mesa stripe, the current blocking layer, and two intermediate layers put between the mesa stripe and the current blocking layer. One of intermediate layers has the p-type conduction and comes in directly contact with the mesa stripe, while, the other intermediate layer has the n-type conduction and put between the former intermediate layer and the current blocking layer. The double intermediate layers prevent impurities in the current blocking layer and in the mesa stripe from inter-diffusing each other.
