Discontinuities in the energies of the conduction and valence bands at semiconductor heterojunctions are important parameters for device design. We describe experiments using X-ray photoelectron spectroscopy with measurements of valence-band energies

Metastable Si 1 − x − y Ge x C y alloys were grown by molecular beam epitaxy on (100) Si substrates. Solid elemental sources were used for the Si and Ge beams, and a resistively heated graphite filament was used for the C beam. Up to 3 at% of C w

Granular Ge films consisting of Ge grains uniformly dispersed in Al and Al2O3 matrices were prepared by magnetron sputtering. Films were deposited by either cosputtering a Ge target and an appropriate matrix target or, as in the case of Al2O3, by spu

Pitch based carbon fibers have been converted to diamond through exposure to a pure hydrogen microwave plasma. The conversion depends strongly on the process pressure. At low pressure only part of the surface of the fiber was converted to diamond, ho
