Fig. 17From: On the p-AlGaN/n-AlGaN/p-AlGaN Current Spreading Layer for AlGaN-based Deep Ultraviolet Light-Emitting DiodesWPE as a function of the injection current for LEDs A, C1, C2, C3, C4, and C5. Inset figure shows the WPE and the EQE for the studied LEDs with various AlN compositions for the n-AlGaN layer at the current density of 170 A/cm2Back to article page
