AlGaInP multiquantum-well (MQW) light-emitting diodes (LEDs), with the n-type modulation-doped (MD) structure, were grown by metal-organic vapor-phase epitaxy. On investigation, these n-type MD-MQW LEDs exhibited a higher luminescence (2.53 lm) and a higher luminous efficiency (16.05 lm/W) than those of conventional LEDs (2.04 lm and 14.49 lm/W, respectively). The junction temperature of the MD-MQW LEDs also showed the benefits of this structure over conventional LEDs with a 14°C reduction achieved at 150mA.
