A variety of methods have been proposed to assemble nanowires on a substrate.Among the methods, electric field has been frequently used to orient, attract, and assemble nanowires.When an AC electric field is applied in a medium including nanowires, an electric dipole is induced on the nanowires to generate dipole moment.Dielectrophoresis induced by the dipole moment attracted and oriented nanowires to the electrodes[1].The usage of a composite field was successfully demonstrated to have the capability of taking advantage of both AC and DC fields[2].In addition, electric field induced methods showed a great potential in one dimensional (a)ssembly of nanotubes [3, 4].The manufacturing process, production rate, and yield, however, should be improved to develop a reliable assembly method.The underlying physics need to be investigated to pave the way to large scale manufacturing using electric fields.
