Abstract:
1. A nanofiber fabrication method for nanofiber growth from a catalyst zone, the method comprising the following steps: producing at least one micropattern on the surface of a substrate, said micropattern having a base, partially convergent sidewalls and an upper face; producing a catalyst zone on the upper face of the micropattern; covering the base with a poison layer for preventing nanofiber growth catalysis; preventing the poison layer from covering the upper face; covering the poison layer on the base with a catalyst layer; dewetting the catalyst zone to form a droplet on the upper face of the micropattern by heating the substrate, wherein the droplet on the upper face is substantially larger than any and all droplets on the sidewalls; and growing the nanofiber from the droplet in the presence of a target; the thickness of the poison layer and the thickness of the catalyst layer being such that no nanofibers are grown on the sidewalls or on the base.
