Abstract
Embodiments of the invention include a III-nitride semiconductor structure comprising a light emitting region disposed between an n-type region and a p-type region. At least one layer in the light emitting region is B(InGa)N. In some embodiments, x is less than 14%. In some embodiments, the BN composition is selected such that the B(InGa)N layer has the same band gap energy as a comparable InGaN layer, with a bulk lattice constant that is the same or smaller than the comparable InGaN layer.
