Buried aperture nitride light-emitting device
摘要:
A buried aperture in a nitride light emitting device is described. The aperture is formed in an aperture layer, typically an amorphous or polycrystalline material over an active layer that includes a nitride material. The aperture layer material typically also includes nitride. The aperture layer is etched to create an aperture which is filled with a conducting material by epitaxial regrowth. The amorphous layer is crystallized forming an electrically resistive material during or before regrowth. The conducting aperture in the electrically resistive material is well suited for directing current into a light emitting region of the active layer.
