Abstract:
Techniques, devices, and systems are disclosed and include LEDs with a first flat region, at a first height from an LED base and including a plurality of epitaxial layers including a first n-layer, a first active layer, and a first p-layer. A second flat region is provided, at a second height from the LED base and parallel to the first flat region, and includes at least a second n-layer. A sloped sidewall connecting the first flat region and the second flat region is provided and includes at least a third n-layer, the first n-layer being thicker than at least a portion of third n-layer. A p-contact is formed on the first p-layer and an n-contact formed on the second n-layer.
