Patent ID: 8684749

Claim:
A method for fabricating a light emitting device comprising: growing an epitaxial n-type semiconductor layer on a substrate, said epitaxial n-type semiconductor layer including random dislocations; growing an active layer comprising a plurality of sub-layers on said epitaxial n-type semiconductor layer under growth conditions that cause pits to form in said active layer, said pits located on said random dislocations, a plurality of said sub-layers having sidewalls that are bounded by said pits; etching said active layer to expose sidewalls of said sub-layers in said pits; growing an epitaxial p-type semiconductor layer over said active layer such that said epitaxial p-type semiconductor layer extends into said pits and contacts said exposed sidewalls of said sub-layers; and providing contacts for applying a potential difference between said epitaxial p-type semiconductor layer and said epitaxial n-type semiconductor layer.
