Abstract
In one aspect, the LEDs in an LED array include a semiconductor mesa and a ruthenium reflector positioned above the top surface of the semiconductor mesa. Working downwards from the ruthenium reflector, the mesa includes a top p-layer, an active region such as a quantum well region, and a bottom n-layer. The n- and p-layers may be reversed, so that the top layer is an n-layer and the bottom layer is a p-layer. The semiconductor layers have a mesa shape, with a smaller top surface and the ruthenium reflector above that. The sidewalls of the mesa extend downwards and outwards from the top surface.
