Carbon nanowires (CNWs) spontaneously formed on the surface of a freshly cleaved highly ordered pyrolytic graphite (HOPG) wafer have been observed for the first time by atomic force microscopy (AFM), an ultrahigh vacuum scanning tunneling microscopy (UHV-STM), and a scanning electron microscopy (SEM). The observed CNWs grow straight on the surface of one terrace or across the step edges with a diameter range from ${\sim}10$ to 200 nm and have ametallic conductivity. The growth of such CNWs seems to originate from surface defects such as step edges and protrusions during the fabrication of the HOPG wafer, or by the rolling of graphene layers into cylinders during cleavage. This result has provided a new method of obtaining CNWs.
