C₆₀/collapsed carbon nanotube hybrids: a variant of peapods.
نویسندگان
چکیده
We examine a variant of so-called carbon nanotube peapods by packing C60 molecules inside the open edge ducts of collapsed carbon nanotubes. C60 insertion is accomplished through a facile single-step solution-based process. Theoretical modeling is used to evaluate favorable low-energy structural configurations. Overfilling of the collapsed tubes allows infiltration of C60 over the full cross-section of the tubes and consequent partial or complete reinflation, yielding few-wall, large diameter cylindrical nanotubes packed with crystalline C60 solid cores.

Electronic and Transport Properties of Carbon Nano Peapods
We theoretically studied the electronic and electrical properties of metallic and semiconducting peapods with encapsulated C60 (C60@CNT) as a function of the carbon nanotube (CNT) diameter. For exothermic peapods (CNT diameter > 11.8 Å), only minor changes, ascribed to a small structural deformation of the nanotube walls, were observed. These include a small electron charge transfer (less than ...

متن کاملEnergetics and packing of fullerenes in nanotube peapods
We use structure-optimization techniques to study the equilibrium packing of fullerenes in carbon nanotube peapods. Our results for nanotubes containing Cn fullerenes with 60ønø84 atoms indicate that the fullerenes are more densely packed in the nanotubes than in the bulk crystal, in agreement with experimental data. We find that the reduction of the interfullerene distance, as well as a struct...
متن کاملThermal conductivity of carbon nanotube peapods
Thermal conductivity of a s10,10d carbon nanotube filled with C60 fullerenes (or a peapod) is computed using direct molecular-dynamics simulations with the Tersoff-Brenner potential for C-C bonding interactions and the van der Waals potential for nonbonding interactions. The temperature-dependent thermal conductivity of the peapod, while showing qualitatively similar behavior to that of an unfi...
متن کاملNanoelectromechanical coupling in fullerene peapods probed by resonant electrical transport experiments.
Fullerene peapods, which are carbon nanotubes encapsulating fullerene molecules, can offer enhanced functionality with respect to empty nanotubes. Their prospective applications include, for example, data storage devices, single-electron transistors and spin-qubit arrays for quantum computing. However, the present incomplete understanding of how a nanotube is affected by entrapped fullerenes is...
