A monolithic white light emitting diode using a (Ga,In)N/GaN multiple quantum well (MQW) light converter is demonstrated. Blue photons emitted under electrical injection by (Ga,In)N/GaN QWs located inside a GaN p-n junction are partly absorbed by another (Ga,In)N/GaN MQW situated outside the junction which emits yellow-green light. The combination of the blue and yellow-green components results in white light emission.

    It is shown that the current collected by a p-n junction in presence of a unit point generation of carriers at a point P is the same (apart from the dimensions) as the excess minority-carrier density at P due to a unit density of carriers at the junction edge. Use of this reciprocity relation...
