Abstract:
1. A Light Emitting Diode (LED) device for emitting non-monochromatic light, the LED device comprising: a substrate layer; a low resistance layer disposed over the substrate layer, wherein the low resistance layer includes a plurality of periods, and wherein at least one of the periods of the low resistance layer includes an aluminum-gallium-nitride sublayer and a gallium-nitride sublayer; an n-type layer disposed over and in contact with the low resistance layer, and wherein the n-type layer has a thickness of more than at least five hundred nanometers; an active layer disposed over the n-type layer, wherein the active layer includes a plurality of periods, and wherein at least one of the periods of the active layer includes an indium-gallium-nitride sublayer and a gallium-nitride sublayer; a p-type layer disposed over the active layer; a first electrode disposed on and in electrical contact with at least a portion of the n-type layer; and a second electrode disposed on and in electrical contact with at least a portion of the p-type layer, and wherein current flow between the first and second electrodes causes the non-monochromatic light to be emitted and to pass through the p-layer.
