Summary :

This paper focuses on the processing of carbon nanotubes (CNTs) alignment as molecular bridge. A magnitude of an alternative voltage of about 1 V with 1 MHz was applied between two electrodes containing CNTs in suspension. The CNT bundles were well stretched along the field line distribution. Two kinds of directions could be distinguished around the electrode: the parallel and the Gaussian. On the other hand, different lengths of CNT bundles were aligned from one electrode side to the other. Those which were more than 1 µm reached both sides of electrodes while the short one did not but followed the Gaussian distribution of electric field. The short CNTs represent an increasing interest of study as far as their flexibility, mechanical and electrical properties are concerned. That's basically because one of their sides ended on the substrate. Among the advantages of the alignment of the CNT is to control the current flux and the thermal conductivity in composite resins or as new materials for the development of novel single-molecular transistors.
