Electrochemical epitaxial polymerization of single-molecular wires

Abstract

Here we have demonstrated a unique single-molecular processing-technique using electrochemistry, called 'electrochemical epitaxial polymerization'. This technique is based on a step-by-step electropolymerization of monomer along the lattice of electrode-surface by applying voltage-pulses into monomer-electrolyte solution. We have succeeded in building a uniform high-density array of single conjugated-polymer wires on electrode as long as 75 nm, with controlling wire's density, length, direction.
