Claim Text:
1. A semiconductor light emitting device comprising: a first semiconductor layer, the first semiconductor layer being doped a first conductive type and including dislocations therein; a pit enlarging layer on the first semiconductor layer; an active layer on the pit enlarging layer, an upper surface of the pit enlarging layer and side surfaces of the active layer defining pits having sloped surfaces on the dislocations, the pits being reverse pyramidal spaces that extend through the active layer into the pit enlarging layer; a hole injection layer on a top surface of the active layer and the sloped surfaces of the pits, the hole injection layer extending into the pits through the active layer; and a second semiconductor layer on the hole injection layer, the second semiconductor layer being doped a second conductive type that is different than the first conductive type, an energy level of the second semiconductor layer being greater than an energy level of the hole injection layer.
