Abstract
A light emitting diode (LED) includes a n-doped semiconductor material layer located over a substrate, an active region including an optically active compound semiconductor layer stack configured to emit light located over the n-doped semiconductor material layer, a p-doped semiconductor material layer located over the active region and containing a nickel doped surface region, a conductive layer contacting the nickel doped surface region of the p-doped semiconductor material, and a device-side bonding pad layer electrically connected to the conductive layer.
