We present a hybrid approach that combines top-down fabrication with bottom-up directed assembly for making single-walled carbon nanotube (SWNT) based three-dimensional interconnects. The SWNTs are assembled using dielectrophoresis at room temperature on a microfabricated 3D platform. The two-terminal resistance of the assembled SWNTs at 10 Vpp assembly voltage is approximately 545 Ω. Simulatio...

This paper proposes the carbon nano structures particularly Carbon nanotube (CNT), Graphene Nanoribbon (GNR), with excellent electrical, thermal and mechanical properties making them an emerging alternative for future onchip interconnect applications. Analysis of CNT and GNR as onchip interconnect has been performed with the help of existing equivalent circuit model. Performance metrics such as...

The vibrational properties (phonons) of a one-dimensional periodic phase of atoms physisorbed in the external groove of the carbon nanotube bundle are studied. Analytical expressions for the phonon dispersion relations are derived. The derived expressions are applied to Xe, Kr and Ar adsorbates. The specific heat pertaining to dense phases of these adsorbates is calculated. PACS numbers: 65.80....

A fabrication strategy is proposed to enable precise coverage of as-grown carbon nanotube (CNT) mats atop vertically aligned silicon nanowire (VA-SiNW) bundles in order to realize a uniform bundle array of CNT-SiNW heterojunctions over a large sample area. No obvious electrical degradation of as-fabricated SiNWs is observed according to the measured current-voltage characteristic of a two-termi...

In this study, we synthesized an organic electrochemical transistor (OECT) using dielectrophoresis of a carbon nanotube-Nafion (CNT-Nafion) suspension. Dielectrophoretically aligned nanowires formed a one-dimensional submicron bundle between triangular electrodes. The CNT-Nafion composite nanowire bundles showed p-type semiconductor characteristics. The drain-source current decreased with incre...

Optical characterization of DNA-wrapped CoMoCAT carbon nanotube hybrids (DNA–CNT) and semiconductor-enriched DNA–CNT was carried out using resonant Raman spectroscopy (RRS) and photoluminescence (PL) experiments. The values of radial breathing modes frequency xRBM were found to be relatively insensitive to the type of wrapping agents surrounding the nanotube. The values of xRBM and the first an...

We report the first measurement of the structure of 4He atoms adsorbed on bundles of single-walled carbon nanotubes. Neutron diffraction techniques and nanotube samples closed at the end were used. At low coverage, 4He forms a 1D, single line lattice along the grooves between two nanotubes on the surface of the nanotube bundles. As coverage is increased, additional lines of 1D lattices form alo...
