In this study, for assembling the nanorods which are synthesized by electrochemical deposition (ECD) method, computer simulation tool (AnsysTM) was used basis of dielectrophoresis (DEP) principle. Following the simulation results, the nanorods assembly device was designed and fabricated using semiconductor technology. Furthermore, an electric field was applied on the assembly electrode with AC bias and DC bias hybrid. The nanorods assembling experiments were carried out as the frequency of the electric field changed. The assembly results were confirmed using optical microscope.
