Abstract

We fabricated a light-emitting diode (LED) having a nitride-rich GaN1-xPx single quantum well (SQW) structure grown using laser-assisted metal-organic chemical vapor deposition (LA-MOCVD). The peak energy of the electroluminescence (EL) of the LED was 2.88 eV, which is in the vicinity of the energy due to the recombination of the bounding exciton by P atoms, known as an isoelectronic trap in GaN. We observed a blue shift of this peak by increasing the drive current. We also observed extra emission of band-to-band recombination at about 3.4 eV above a drive current of 32 mA, where the external quantum efficiency was already saturated.
