<P>PROBLEM TO BE SOLVED: To provide a light-emitting diode which prevents occurrence of lattice defect. <P>SOLUTION: A light-emitting diode 10 comprises: a substrate 100; a first semiconductor layer 120; a second semiconductor layer 140; an activation layer 130; a first electrode 150; and a second electrode 160. The first semiconductor layer, the activation layer, and the second semiconductor layer are sequentially stacked on the substrate along a direction away from the substrate. The first electrode is electrically connected to the first semiconductor layer. The second electrode is electrically connected to the second semiconductor layer. A surface of the first semiconductor layer that is adjacent to the substrate is a carbon nanotube layer 102 which is patterned so as to include a plurality of gaps. Since the patterned surface of the first semiconductor layer is connected to the substrate, a plurality of cavities are formed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
