摘要： A growth mask layer including an array of apertures therethrough can be formed on a single crystalline gallium nitride layer. Group III nitride nanostructures including gallium nitride or indium gallium nitride nanopyramids or nanowires can be formed through the array of apertures by a selective epitaxy process. An indium gallium nitride material can be deposited by another selective epitaxy process on the Group III nitride nanostructures until a continuous indium gallium nitride template layer is formed. The continuous indium gallium nitride template layer has a dislocation density that decreases with distance from the growth mask layer. Red light emitting diodes can be formed over the continuous indium gallium nitride template layer with higher efficiency due the relatively large lattice constant of the continuous indium gallium nitride template layer.

摘要： A direct view multicolor light emitting device includes blue, green and red light emitting diodes (LEDs) in each pixel. The different light emitting diodes can be formed by depositing different types of active region layers in a stack such that deposition area of each subsequent active region is less than the deposition area of any preceding active region, and by patterning the active region layers into different types of stacks. The active region layers may be formed as planar layers, or may be formed on semiconductor nanowires. The active region layers can emit light at the respective target wavelength range. Alternatively, at least one of green and red phosphor materials, dye materials, or quantum dots may be used instead of or in addition to the active regions that emit light at a wavelength different from a target wavelength of a respective LED.
