Figure 5From: Improved light extraction of InGaN/GaN blue LEDs by GaOOH NRAs using a thin ATO seed layerRoom-temperature EL spectra of LEDs with and without GaOOH NRAs at various injection currents. The inset shows the illumination images of the fabricated LEDs with/without GaOOH NRAs at an injection current of 5 mA.Back to article page
