Light-Emitting Diode Chip

摘要

A thin-film light-emitting diode chip, in which the distance between a mirror layer ( 4 ) and a light-generating active zone ( 3 ) is set in such a way that a radiation emitted by the active zone ( 3 ) interferes with a light reflected from the mirror layer ( 4 ), the internal quantum efficiency of the active zone ( 3 ) being influenced by this interference and the emission characteristic of the active zone ( 3 ) of at least one preferred direction thereby being obtained.
