Abstract:
1. A method for manufacturing a light-emitting diode, comprising: providing a plurality of protruded portions and a plurality of recess portions on one main surface of a substrate, wherein each protruded portion is made of a material different in type from that of said substrate and each recess portion is defined as space between a respective pair of the plurality of protruded portions; growing, via a first growth temperature, a first nitride-based III-V Group compound semiconductor layer having a triangle cross section on a bottom surface of each recess portion, the bottom surface of each recess portion being a base of the respective triangle cross section; laterally growing, via a second growth temperature, a second nitride-based III-V Group compound semiconductor layer between each of the plurality of protruded portions on said substrate from said triangle cross sections of said first nitride-based III-V Group compound semiconductor layer, the lateral growth being predominant such that together said first and second nitride-based III-V Group compound semiconductor layers substantially have a respective hexagon cross section between a respective pair of the plurality of protruded portions during the lateral growth, each hexagon cross section being perpendicular to the one main surface; and successively growing a third nitride-based III-V Group compound semiconductor layer of a first conduction type, an active layer, and a fourth nitride-based III-V compound semiconductor layer of a second conduction type on said second nitride-based III-V Group compound semiconductor layer, wherein,
