| Abstract: | Single bundles of carbon nanotubes have been selectively deposited from suspensions onto sub-micron electrodes with alternating
electric fields. We show that it is possible to control the trapping of a single bundle by the use of Ag as electrode material
which, unlike Au, strongly interacts with the carboxyl functionalized carbon nanotubes. Excellent alignment of the bundles
between Au or Ag electrodes occurs at frequencies above 1 kHz, with superior contacts being formed with Ag electrodes.
