Formation of the nanoscale contacts structure based on cross-junction of carbon nanotubes for the study of organic materials

Abstract

Using the dielectrophoresis method with unipolar rectangular pulses for the deposition of carbon nanotubes (CNTs), functionalized by COOH groups, single nanosized contacts based on a single-walled CNT and a functionalized single-walled CNT have been formed, the specific contact resistance of which, according to the estimate, was about 0.25 µΩ·cm2 or about 6 MΩ per one cross-junction of CNTs. The possible usage of the proposed technique for the nanoscale contacts formation based on the cross-junction of CNTs in various layers for the study of organic materials and charge transport in a nanoscale channel is considered.
