Abstract:
1. A method of making a light emitting device, comprising: providing a growth substrate comprising a growth mask having a plurality of first apertures in a first area and a plurality of apertures in a second area; selectively growing a plurality of first nanostructures through the first apertures and a plurality of second nanostructures through the second apertures in a same nanostructure growth step, wherein the first and the second nanostructures comprise an inner portion or an entirety of respective first and second growth templates; growing first and second active regions on respective first and second growth templates in the same active region growth step; and growing first and second junction forming elements on respective first and second active regions in a same junction forming element growth step to form respective first and second light emitting devices; wherein each first growth template differs from each second growth template such that each second light emitting device has a second peak emission wavelength different from a first peak emission wavelength of each first light emitting device; and the first and the second light emitting devices comprise light emitting diodes, and each first and second junction forming element is selected from a semiconductor shell, a continuous semiconductor layer which contacts plural growth templates, or a continuous semiconductor layer with interstitial voids which contacts plural growth templates.
