Nano-/micro metallic wire synthesis on Si substrate and their characterization

Abstract

Nano-/micro wires of copper are grown on semiconducting Si substrate using the template method. It involves the irradiation of 8 um thick polymeric layer coated on Si with150 MeV Ni ion beam at a fluence of 2E8. Later, by using the simple technique of electrodeposition, copper nano-/micro wires were grown via template synthesis. Synthesized wires were morphologically characterized using SEM and electrical characterization was carried out by finding I-V plot.

“…Amongst the physical processes, ion irradiation on materials specially polymer induce latent track of nanometer dimension (10‐100 nm) along the path of the ion projectile due to its large electronic energy deposition which is either spent in relocating atoms of the polymer through elastic collisions ( S n ) or exciting the atoms by inelastic collisions ( S e ) ,. The creation of ion track occurs when S e is more than a threshold value which varies from polymer to polymer.…”
