Effects of multiple interruptions with trimethylindium-treatment in the InGaN/GaN quantum well on green light emitting diodes |
(a) PL spectra of LEDs A and B at 300 K. The FWHM values of LEDs A and B are 22 nm and 27 nm respectively. (b) EL spectra of LEDs A and B at 20 mA. The integrated EL intensity of LED A is about 1.4 times higher than that of LED B. |
