Abstract:
1. A method of synthesizing electronic components incorporating nanoscale filamentary structures, the method comprising: making a nanoporous membrane having a plurality of pores in a thin layer transferred or deposited onto a single-crystal substrate; depositing a metal catalyst in and on the nanoporous membrane, the metal catalyst suitable for penetrating into at least some of the pores of the nanoporous membrane; growing filamentary structures on the catalyst in the at least some of the pores of the nanoporous membrane; wherein the nanoporous membrane is prepared in a manner suitable for ensuring that a wall of the pores includes a single-crystal zone, and wherein at least some of the catalyst is grown epitaxially on said single-crystal zone and on at least a portion of the nanoporous membrane common to numerous pores so that orientation of the nanoscale filamentary structures is controlled relative to one another and so that the chirality of the nanoscale filament structures is also controlled.
