High-density energy deposition using ion beams causes the nonhomogeneous cross-linking reaction of polysilane derivatives within a nano-sized cylindrical area along an ion trajectory, and yields β-SiC-based nanowires whose sizes (length and thickness) and number densities are completely controlled by changing the energy, particle, and fluence of incident ions, and/or molecular sizes of target polymers. Recently, the techniques of position-selective single ion hitting have been developed for MeV order ion beams. However, it is difficult to precisely control the positions of nanowires on substrates. In the present study, we report the selective adhesion of nanowires on Si substrates by surface treatment before polymer coating, which enables the patterning of the planted nanowires on substrates and/or electrodes as candidate, nano-sized field emissive cathodes or electroluminescent devices.
