Presentation Transcript
Conclusion • With increasing injection currents, the band-filling effect and the heating effect on localized energy states are taken into account to explain the disappearance of the temperature-dependent S-shaped peak position and W-shaped FWHM • Moreover, the EL external quantum efficiency of the InGaN/GaN MQWs is also evaluated. It is observed that the EL efficiency is strongly dependent on temperature and injection current.
