Abstract
A light emitting device includes an active layer configured to provide light emission due to carrier recombination therein, a surface on the active layer, and an electrically conductive contact structure on the surface. The contact structure includes at least one plated contact layer. The contact structure may include a sublayer that conforms to the surface roughness of the underlying surface, and the plated contact layer may be substantially free of the surface roughness of the underlying surface. The surface of the plated contact layer may be substantially planar and/or otherwise configured to reflect the light emission from the active layer. Related fabrication methods are also discussed.
