Abstract
Systems and methods describe growing RE-based integrated photonic and electronic layered structures on a single substrate. The layered structure comprises a substrate, an epi-twist rare earth oxide layer over a first region of the substrate, and a rare earth pnictide layer over a second region of the substrate, wherein the first region and the second region are non-overlapping.
