Abstract:
1. A solid-state light emitting structure, comprising: a template structure having a growth surface defining a growth plane, said template oriented such that its primary crystallographic plane is oriented at an angle α that is out of normal to said growth plane; a dielectric layer over and in physical contact with said template structure, said dielectric layer having a plurality of windows formed there, each said window having a structural sidewall over at least a portion of said growth surface and extending substantially normal to said growth plane and defining a plurality of window openings, said window openings having a width, w, and a height, h; a coalescence layer over and in physical contact with said dielectric layer, said coalescence layer including portions extending within said window openings, such that crystallographic defects which originate at a portion of said growth surface and which lie in planes that are substantially parallel to said crystallographic plane of said template substantially terminate at said sidewalls and thereby substantially do not extend beyond the height h of said window openings, said coalescence layer having a substantially planar, continuous, polished upper surface; an active region over said coalescence layer, said active region comprising: a contact layer over said active region.
