Optimization of the Electron Blocking Layer in GaN Laser Diodes
-
Abstract
In view of the transport mechanism of electrical carriers,the factors involved in the current overflow in GaN-based laser diodes are analyzed,and the aluminum mole fraction as well as the p-doping concentration of the AlGaN electron blocking layer are optimized.The results indicate that the appropriate barrier height (the Al mole fraction) is lower when the p-doping concentration is higher.-
