Abstract: Gallium oxide nanowires were grown on different substrates using a corona plasma assisted vapor phase epitaxy process and gold catalyst. It is shown that the silicon carbide pseudo substrate in combination with the plasma excitation of the gas phase supports the growth of the gallium oxide nanowires. Analyzing the orientation of the nanowires with respect to the growth surface, it is concluded that the nanowires growth proceed along the fast growth direction of gallium oxide.

Abstract: Epitaxial graphene was grown on Si-face 4H-SiC. A SiC pretreatment with a carbon cap¬ping technique was used as well as slow heating rates and a temperature of 1800 °C under atmos¬pheric argon pressure. The surface morphology was investigated by atomic force microscopy and Raman spectroscopy was performed for samples with different graphitization times.
