Patent ID: 8853668

Claim:
A light emitting diode (LED), comprising: a first layer comprising an n-type Group III-V semiconductor; a second layer adjacent to the first layer, the second layer comprising an active layer that generates light upon the recombination of electrons and holes and has a thickness between 50 nm and 200 nm; a third layer adjacent to the second layer, the third layer comprising a p-type Group III-V semiconductor; and a silicon substrate adjacent to one of either the first layer or the third layer, wherein the active layer comprises one or more V-pits having one or more openings at an interface between the active layer and the third layer, the V-pits having a density between about 10 V-pits/μm 2 and 20 V-pits/μm 2 at the interface and a density between about 10% and 20% of a surface coverage of the interface.
