ABSTRACT:
Semiconductor light-emitting structures are shown on engineered substrates having a graded composition. The composition of the substrate may be graded to achieve a lattice constant on which a yellow-green light-emitting semiconductor material may be disposed. In some embodiments, the structure may be substantially free of aluminum.
