Various nanowire (or nanotube)-based devices have been investigated to fulfill future demands on semiconducting devices, nanoscale electromechanical systems, and biosensors. To fabricate such devices, an electric field-induced assembly method has demonstrated a great potential for one dimensional assembly. In this paper, our novel approaches for fabricating hybrid nanofibrils are presented to enhance the multiple functionalities, the production rate and the fibril length. These approaches offer unique opportunities for fabricating hybrid nanofibrils composed of silicon carbide (SiC) nanowires and single walled carbon nanotubes (SWCNTs).
