Abstract: Semiconductor devices and methods of fabricating semiconductor devices having a dilute nitride layer and at least one semiconductor material overlying the dilute nitride layer are disclosed. Hybrid epitaxial growth and the use of aluminum barrier layers to minimize hydrogen diffusion into the dilute nitride layer are used to fabricate high-efficiency multijunction solar cells.
