  • Material layer stack, light emitting element, light emitting package, and method of fabricating light emitting element
    Patent number: 9954142
    Abstract: Disclosed herein are a material layer stack, a light emitting element, a light emitting package, and a method of fabricating a light emitting element. The material layer stack includes: a substrate having a first lattice constant; and a semiconductor layer grown on the substrate, the semiconductor layer having a second lattice constant that is different from the first lattice constant. Using the material layer stack, a light emitting element having a low leakage current, a low operation voltage, and an excellent luminous efficiency can be obtained.
    Type: Grant
    Filed: August 19, 2016
