Fig. 1From: Influence of Quantum-Well Width on the Electroluminescence Properties of AlGaN Deep Ultraviolet Light-Emitting Diodes at Different Temperaturesa The RT EL spectra for LEDs A, B, and C under direct current of 100 mA. All the spectra were normalized to the band-to-band emission. b The relative EQE as a function of pulse currentBack to article page
