Abstract

Composite AC - DC dielectrophoresis (DEP) is used to assemble arrays of individual multi-walled carbon nanotubes (MWNTs) onto gold nanoelectrodes. The nanoelectrodes are fabricated on silicon chips using electron-beam lithography. Using suitably designed electrodes for DEP or by electrical breakdown of the assembled nanotubes, individual nanotubes with one end end protruding from an electrode and the other end in proximity to another electrode are realized. Such nanotube arrays can be used as lateral field emitters, nanorelays and in other nanoelectromechanical systems (NEMS).
