Abstract

Ultra-long straight carbon wires with few microns in diameter and centimeters in length were synthesized in large scale through a controllable one-step chemical vapor deposition (CVD) method. The ratio of axial length to diameter more than 1000:1. The scanning electron microscope (SEM) and high-resolution transmission electron microscopy (HRTEM) images prove the layered structure surrounding the wire center, and the energy dispersive spectra (EDS) confirm the main component of the as-obtained carbon wires is carbon. Room temperature Raman spectrum presents two distinct Raman peaks of 1351 cm^-1 (D band) and 1586 cm^-1(G band), which is consistent with carbon crystalline structures. I-V curves exhibit typical resistance characteristic, which can be used as electronic polar or mechanic probe to operate nanostructures.
