Temperature-dependent electroluminescence from InGaN/GaN light-emitting diodes (LEDs) grown on Si (111) are investigated. With the increase of current density, internal quantum efficiencies (IQEs) firstly rise accompanied by full width at half maximum (FWHM) shrinkage and then IQEs droop combined with FWHM broadening are presented. With the decline of temperature, both the maximum of IQEs accompanying the minimum of FWHM shift towards the direction of low current density. Moreover, the maximum of IQEs shift faster than the minimum of FWHM for single quantum well LED. Furthermore, it was found that the quantum well close to n-GaN has priority to radiate in small current injection, especially at low temperature (100 K) for multiple quantum wells LED.
