Influences of screw dislocations on electroluminescence of AlGaN/AlN-based UVC LEDs

Influences of screw dislocations on electroluminescence of AlGaN/AlN-based UVC LEDs

We investigated two types of threading dislocations in high Al-composition Al0.55Ga0.45N/AlN multiple quantum well (MQW) structures grown on AlN substrate for electrically injected deep ultraviolet light-emitting diodes (LEDs). The surface morphology and defects electrical characteristics of the MQW...
