Photoluminescence and electron field-emission properties of SiC-SiO2 core-shell fibers and 3C-SiC nanowires on silicon nanoporous pillar array

► SiC-SiO2 fibers and 3C-SiC nanowires were directly grown on Si-NPA. ► Violet-blue light emitting were obtained in SiC-SiO2/Si-NPA and nw-SiC/Si-NPA. ► Enhanced field-emission property was found in nw-SiC/Si-NPA.
