Abstract
A vertical light-emitting diode (VLED) includes a metal substrate, a p-electrode coupled to the metal substrate, a p-contact coupled to the p-electrode, a p-GaN portion coupled to the p-electrode, an active region coupled to the p-GaN portion, an n-GaN portion coupled to the active region, and a phosphor layer coupled to the n-GaN portion.
