Abstract

A set of light emitting devices can be formed on a substrate. A growth mask having a first aperture in a first area and a second aperture in a second area is formed on a substrate. A first nanowire and a second nanowire are formed in the first and second apertures, respectively. The first nanowire includes a first active region having a first band gap and a second active region having a second band gap. The first band gap is greater than the second band gap. The second nanowire includes an active region having the first band gap and does not include, or is adjoined to, any material having the second band gap.
