Abstract:
1. A system for growing nanostructures, comprising: a porous growth substrate with a first surface portion on a first side of the growth substrate suitable for growing nanostructures thereon, the growth substrate comprising a catalyst material; a first region able to expose the first surface portion of the growth substrate to a first set of conditions selected to cause catalytic formation of nanostructures on the first surface portion of the growth substrate and configured such that a nanostructure precursor material is transported from a second side of the porous growth substrate to the first side of the porous growth substrate; and a second region able to expose the first surface portion of the growth substrate to a second set of conditions, different from the first set of conditions, and selected to remove nanostructures from the first surface portion of the growth substrate while the first region exposes a second surface portion of the growth substrate to a set of conditions selected to cause catalytic formation of nanostructures on the second surface portion of the growth substrate.
