Fabrication and transport properties of multiwall carbon nanotube crossroads

Noncovalent Control for Bottom-Up Assembly of Functional Supramolecular Wires

“…1 Candidate components for the wires in the circuits are generally considered to be conventional metals 2 or carbon nanotubes. 3 We report here preparation of supramolecular wires 4 using a bottom-up 5 and conceptual alternative to these strategies, using organic molecules which are selfassembled 6 at a surface under ambient conditions in a liquid. The wire-like system shows a small experimental conductance gap, and quantum-chemical calculations predict favorable charge transport along the π-electron-rich cores.…”

Charge Transport in Organic Semiconductors: A Multiscale Modeling

“…Candidate components for the wires in the circuits are generally considered to be conventional metals [94] or carbon nanotubes [95]. However, several reports have shown the possibility to form supramolecular wires [96,97] by a bottom-up approach [98], using organic molecules that self-assemble [99] at a surface under ambient conditions from a solution.…”

The transport property at cross-junction of multiwall carbon nanotubes

“…In this study, we have succeeded to measure the real conductance at the junction of MWNTs using a four-terminal (4-t) method. In order to fabricate the crossed structure, we have established our original manipulation technique [7] and the transport properties have been studied by multi-terminal measurements.…”
