  We compute electrostatic fields induced deformations of cantilevered
finite-length metallic carbon nanotubes, using an energy minimization method
based on a charge-dipole moment interaction potential combined with an
empirical many-body potential. The influence of field strength, field direction
and tube geometry on the electrostatic deflection is investigated for both
single and double walled tubes. These results could apply to
nanoelectromechanical devices based on cantilevered carbon nanotubes.
