摘要：
Structures for transitioning between two layers of differing lattice parameters are disclosed. In some embodiments, the structures are in the form of a superlattice that serves as a strain relieving transition between two layers of differing lattice parameters. By controlling the properties of the superlattice, the superlattice can exhibit desirable properties such as transparency to light and lattice matching to one of the two layers of differing lattice parameters. Optoelectronic devices such as light emitting diodes including such superlattices are also disclosed.
