2-D Electric Field Assisted Assembly of Single Carbon Nanotubes and the Effect on the Applied Field
Abstract
This paper reports on research work on electric field assisted assembly of single carbon nanotubes onto microcircuit electrodes, and the effect of the carbon nanotubes on the electric field. The research supports the development of nanoelectronics for reducing weight in military systems. A simulation method of assembly processes of carbon nanotubes by dielectrophoresis is introduced. The method considers the effect of carbon nanotubes on the electric field. A calculation model of the dielectrophoretic force based on the effective dipole moment method is presented. The model divides a carbon nanotube into multiple segments, computes the dielectrophoretic force for each segment and sums all of the forces to get a total effect. Compared to the field nonuniformity around the whole carbon nanotube, the field non-uniformity around each segment is reduced, leading to increased computational accuracy. The method can be used to simulate the dielectrophoretic assembly processes of a carbon nanotube originally located at any position of the electric field and the numerical results help to analyze carbon nanotube assembly processes and to optimize the process controlling parameters.
