We report on the fabrication and electrical characterization of active nanoscale electronic devices using single vertically aligned carbon nanofibers (VACNFs). A rectifying behavior consistent with a 0.3 eV Schottky barrier was found. Experimental results indicate that a region of semiconducting SiC is formed directly beneath the VACNF during the growth process, creating the Schottky-barrier junction between this semiconductor material and the metallic carbon nanofibers.
