“…The previous VA-SWNT1 batch has been grown in a steady ethanol vapor stream 22 and the current VA-SWNT2 batch has been grown in static ethanol vapor. 15 The higher density and thickness of the present thinbundled VA-SWNT forests is also an experimental necessity to perform inelastic x-ray scattering.…”

The dynamical structure factor S͑q , ͒ in graphite, freestanding thin-bundled single-walled carbon nanotubes and bulk aligned nanotubes is probed by means of inelastic x-ray and electron scattering. We utilize the equivalency and complementarity of the two techniques in our combined approach. Both independent methods may be joined seamlessly. The joint extended experimental access to the plasmon dispersion exposes vividly the transition from screened plasmons at low momenta to uniform interband transitions at high momentum transfers.

“…15 Two as-grown films were removed from their quartz substrates using warm water and transferred onto standard Cu TEM grids. 16 The total thickness of the stacked vertically aligned SWNTs is ϳ100 m. The grid-supported SWNTs as well as empty TEM reference grids were mounted over a 2-mm-wide slit in a 20ϫ 20ϫ 1 mm steel plate.…”

“…The proposed technique has advantages in improved simplicity and potentially better resolution compared to conventional lithography. Related to our previous finding that no-flow ACCVD is suited for growth of longer VA-SWNTs (16), some updated understanding of the decomposition of ethanol in ACCVD is also presented (17).…”

Carbon nanotubes and graphene are extra-ordinal material with remarkable electrical, optical, mechanical and thermal properties. Films of vertically aligned (VA-) SWNTs and horizontally aligned (HA-) SWNTs are synthesized on quartz and crystal quartz substrates, respectively. These aligned film should inherit the remarkable properties of SWNTs. The recent progress in growth control and characterization techniques will be discussed. The CVD growth mechanism of VA-SWNTs is discussed based on the in-situ growth monitoring by laser absorption during CVD. For the precisely patterned growth of SWNTs, we recently propose a surface-energy-difference driven selective deposition of catalyst for localized growth of SWNTs. For a self assembled monolayer (SAM) patterned Si surface, catalyst particles deposit and SWNTs grow only on the hydrophilic regions. The proposed all-liquid-based approach possesses significant advantages in scalability and resolution over state-to-the-art techniques, which we believe can greatly advance the fabrication of nano-devices using high-quality asgrown SWNTs. The optical characterization of the VA-SWNT film using polarized absorption, polarized Raman, and photoluminescence spectroscopy will be discussed. The extremely high and peculiar thermal conductivity of single-walled carbon nanotubes has been explored by nonequilibrium molecular dynamics simulation approaches. The thermal properties of the vertically aligned film and composite materials are studied by several experimental techniques and Monte Carlo simulations based on molecular dynamics inputs of thermal conductivity and thermal boundary resistance. Current understanding of thermal properties of the film is discussed.

“…[8][9][10] Briefly, bimetallic Co/Mo catalyst particles were obtained by dip-coating Si substrates into separate Mo-acetate and Co-acetate solutions containing 0.01 wt.% of the respective metal species. After reducing the dip-coated substrate under flowing Ar/H 2 (3% H 2 ), the CVD chamber was evacuated and sealed.…”

The unexpected presence of a linear arrangement of co-axially oriented N 2 molecules inside aligned single-walled carbon nanotubes is revealed by high resolution near-edge x-ray absorption spectroscopy. The encapsulated N 2 molecules exhibit free stretching vibrations with a long electronic lifetime of the x-ray-excited anti-bonding π ⋆ states. Molecular dynamics simulations confirm that narrow-diameter nanotubes (d < 1 nm) are crucial for stabilizing the linear arrangement of aligned N 2 molecules.
