Abstract:
1. A light emitting diode comprising: an epitaxial substrate; an active layer including a first conductive type film that is disposed on said epitaxial substrate, a quantum well structure that is formed on said first conductive type film, and a second conductive type film that is formed on said quantum well structure, said active layer being able to generate light which has a wavelength smaller than 400 nm when applied with an external electric energy, said second conductive type film being made from Al a tunneling layer stacked on and contacting said second conductive type film and made from Al a current spreading layer stacked on and contacting said tunneling layer; and an electrode unit electrically connected to an assembly of said active layer, said tunneling layer and said current spreading layer for transmitting the external electric energy to the assembly of said active layer, said tunneling layer and said current spreading layer.
