Combination of strain management layers for light emitting elements

Abstract

The disclosure describes various aspects of strain management layers for light emitting elements such as light-emitting diodes (LEDs). The present disclosure describes an LED structure formed on a substrate and having a strain management region supported on the substrate, and an active region configured to provide a light emission associated with the LED structure. The strain management region includes a first layer including a superlattice having a plurality of repeated first and second sublayers, and a second layer including a bulk layer. In an embodiment, at least one of the first and second sublayers and the bulk layer includes a composition of InxAlyGa1-x-yN. A device having multiple LED structures and a method of making the LED structure are also described.

Dependencies are inferred from the claim text.
