Abstract
Described are light emitting diode (LED) devices having a patterned dielectric layer on a substrate and methods for effectively growing epitaxial III-nitride layers on them. A nucleation layer, comprising a III-nitride material, is grown on a substrate before any patterning takes place. The patterned dielectric layer comprises a first plurality of features and a second plurality of features, where the second plurality of features has a height larger than the height of the first plurality of features. The second plurality of features aligns with the cathode layer of the trench.
