    Substrate and size effects on the coalescence of small particles (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 70 (1991), S. 5138-5140 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: Here we present experimental results, using high-resolution electron microscopy and real time video recording, on the liquid-like coalescence of small gold particles supported on silica. We report that particles that are few nanometers in size, and decoupled from substrate interactions, coalesce extremely fast, in fractions of a second. When the particles are properly supported on a substrate, coalescence is orders of magnitude slower, depending on the particle size, and influenced by the diffusion of atoms on the substrate surface. Necks are seen to develop distinctly during coalescence only for particles above certain size.

    Lift-up growth of aligned carbon nanotube patterns (2000)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 77 (2000), S. 2985-2987

    Topics: Physics
    Notes: The fabrication of three-dimensional networks of carbon nanotubes with controlled orientation will be essential for building large-scale functional devices integrated with microelectronics circuits. We describe here our recent work on the controlled synthesis of vertically aligned carbon-nanotube patterns, grown under patterned metal layers on Si substrates by combining chemical-vapor deposition and conventional lithography. We show that metal patterns are lifted up by vertically aligned nanotubes during growth. This lift-up growth links the thin-film metal patterns and the Si substrate via nanotube assemblies, giving the possibility of creating nanotube architectures in three dimensions. The possible scenarios of the growth of aligned nanotube films leading to the lift up of the metal films are discussed. © 2000 American Institute of Physics.

    Reliability and current carrying capacity of carbon nanotubes (2001)

    Notes: The current-carrying capacity and reliability studies of multiwalled carbon nanotubes under high current densities (〉109 A/cm2) show that no observable failure in the nanotube structure and no measurable change in the resistance are detected at temperatures up to 250 °C and for time scales up to 2 weeks. Our results suggest that nanotubes are potential candidates as interconnects in future large-scale integrated nanoelectronic devices. © 2001 American Institute of Physics.

    Growth, structure, and optical properties of carbon-reinforced silica fibers (2001)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 78 (2001), S. 3794-3796

    Topics: Physics
    Notes: We report the synthesis of carbon-reinforced silica fibers by methane exposure of metallocene-treated oxidized-Si(001) substrates at 1100 °C. The SiO2 cap layer transforms into silica fibers reinforced by glassy carbon in the core during methane exposure. High-resolution electron microscopy and spatially resolved spectroscopy measurements of the fibers reveal an amorphous structure without a hollow, and domains of glassy carbon embedded at the fiber core. The carbon-reinforced fibers are optically transparent and have an optical band gap of (similar, equals)3.1 eV. These fibers are organized in radial patterns that vary for different metallocene species. On nickelocene-treated substrates, the fibers originate from the circumference of the circular templates and grow outwards, forming radial patterns. On ferrocene-treated substrates, randomly oriented fibers grow within as well as slightly outside the perimeter of the templates, forming wreath-like patterns. Aligned growth of such fibers could be useful for fabricating optoelectronics devices and reinforced composites. © 2001 American Institute of Physics.

    Load transfer in carbon nanotube epoxy composites (1998)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 73 (1998), S. 3842-3844 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The mechanical behavior of multiwalled carbon nanotube/epoxy composites was studied in both tension and compression. It was found that the compression modulus is higher than the tensile modulus, indicating that load transfer to the nanotubes in the composite is much higher in compression. In addition, it was found that the Raman peak position, indicating the strain in the carbon bonds under loading, shifts significantly under compression but not in tension. It is proposed that during load transfer to multiwalled nanotubes, only the outer layers are stressed in tension whereas all the layers respond in compression. © 1998 American Institute of Physics.

    Substrate-site selective growth of aligned carbon nanotubes (2000)

    Topics: Physics
    Notes: We report highly substrate-site selective growth of carbon nanotubes by chemical vapor deposition from precursors of ferrocene and xylene mixtures. The technique allows us to grow well-aligned multiwalled carbon nanotubes preferentially on the SiO2 regions of patterned SiO2/Si substrates prepared by conventional lithography. This eliminates the catalyst predeposition step in the fabrication process. This simple approach may also be applied to build large-scale networks of organized nanotubes on planar substrates. © 2000 American Institute of Physics.

    Growth of aligned carbon nanotubes on self-similar macroscopic templates (2002)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 81 (2002), S. 1297-1299 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We demonstrate a two-step chemical vapor deposition process to obtain carbon nanotube (CNT) networks using aligned nanotube films themselves as growth templates. Track patterns of exposed silica created in CNT films grown in the first step serve as macroscopic templates for growing CNT stripes in the second step. The nanotubes in both the template and the stripes are vertically aligned. The CNT templates can be selectively removed while retaining the network of CNT stripes grown among them in the predefined patterns. Two-step processes such as described here will be of interest for creating multilayered CNT architectures through pattern transfer and growth sequences. © 2002 American Institute of Physics.
