Controlled deposition of carbon nanotubes (CNTs) across desired electrodes is important
for the fabrication of nanoelectronic devices. Dieletrophoresis (DEP) has been recognized as a
convenient and affordable technique for the deposition of nanotubes and nanowires on
electrodes. Although DEP has been quite well studied for dielectric particles, the application for
depositing nanotubes is still at the early stage of development. Here, we show that multi-walled
CNTs can be deposited by DEP with controllable density and degree of alignment.
