摘要：
A high-efficiency light-emitting element includes a substrate, a first nitride semiconductor layer formed on the substrate, a nitride light-emitting layer formed on the first nitride semiconductor layer, and a second nitride semiconductor layer formed on the nitride light-emitting layer including a plurality of hexagonal-pyramid cavities on the surface of the second nitride semiconductor layer opposite to the nitride light-emitting layer.
