Abstract: The authors demonstrate 3-D directed assembly of single-wall carbon nanotubes (SWNT) into porous alumina nanotemplates on silicon substrates by means of electrophoresis and dielectrophoresis at ambient temperatures.
This manipulation is performed by means of non-uniform electric fields generated with interdigitated electrodes of 70 mm in size, which can originate the common dielectrophoresis phenomenon.
