Query: Contacting single bundles of carbon nanotubes with alternating electric
  fields   Single bundles of carbon nanotubes have been selectively deposited from
suspensions onto sub-micron electrodes with alternating electric fields. We
explore the resulting contacts using several solvents and delineate the
differences between Au and Ag as electrode materials. Alignment of the bundles
between electrodes occurs at frequencies above 1 kHz. Control over the number
of trapped bundles is achieved by choosing an electrode material which
interacts strongly with the chemical functional groups of the carbon nanotubes,
with superior contacts being formed with Ag electrodes.
