Hybrid Nanowire Growth via Field Emission based on Nanorobotic Manipulation

Abstract

Abstract This paper presents the hybrid nanowire growth via field emission based on nanorobotic manipulations inside field emission scanning microscope (FESEM). The hybrid nanowires are made of different kinds of materials. A multi-walled carbon nanotube (MWNT) was used as an emitter. A tungsten probe was positioned as anode at counter position by nanomanipulation. By changing the trimethyl cyclopentadienyl platinum (CpPtMe 3 ) and tungsten hexacarbonyl (W(CO) 6 ) as precursors, the metallic nanowires were grown via field emission for several minutes. The growth processes was repeated to control the length of nanowires. Finally, the hybrid nanowire was fabricated by growing the tungsten nanowires at the tip of platinum nanowire. The components of hybrid nanowires were evaluated by the energy-dispersive X-ray spectroscopy (EDS) of transmission electron microscope (TEM). The hybrid nanowire has various applications in nanoelectronics, nanosensor device, nanomechanical system and so on.
