Fig. 8From: 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, T1, T2, T3, T4, and T5. Inset figure shows the WPE and EQE for the studied LEDs with various thicknesses of the n-Al0.40Ga0.60N layer for the PNP-AlGaN junction at the current density of 170 A/cm2Back to article page
