ABSTRACT
Infrared and atomic composition measurements of a-Si[ATOTHER]@B:[/ATOTHER] H/a-SiNx[ATOTHER]@B:[/ATOTHER] H superlattices as a function of repeat distance show ∼1×1015 cm-2 extra hydrogen bonded to Si at the interface formed when a-Si:H is deposited on a-SiNx[ATOTHER]@B:[/ATOTHER] H. The H distribution peaks in the first monolayer and decays in the a-Si:H layer over a distance of ∼19 Å. The hydrogen relieves the large lattice mismatch between the two layers and pacifies defects.
