    High-purity vapor phase purification of C60 (1994)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: A method is described which utilizes the difference in vapor pressure between C60 and heavier fullerenes to produce ultrahigh purity C60. Fullerene extract is introduced into one end of a distillation column with a series of evenly spaced perforated baffles inside. The extract is heated to 970 K under high vacuum, and a linear temperature gradient is established along the column. As the mixed fullerene vapor effuses down the column, it becomes enriched in the more volatile species. C60 with a purity of 99.97% has been obtained. This method shows promise in the purification of more exotic fullerene compounds.

    Epitaxial integration of single crystal C60 (1993)

    Notes: Single crystal thin films of (111) oriented C60 are grown on epitaxial layers of single crystal antimony. The C60/Sb epitaxy is confirmed by low-energy electron diffraction which indicates that the [11¯0] in-plane directions are parallel in the two layers. X-ray diffraction shows that the C60 film is entirely (111) oriented and of high quality with sharp Bragg peaks and narrow mosaic spread. In this study the Sb films were grown on GaSb, to which they are lattice matched; however, since Sb can be epitaxially grown on surfaces with a large lattice mismatch this technique may be applied to integrate C60 single crystals onto many substrates or devices with a surface having sixfold symmetry.

    Time-resolved reflectivity studies of the GaAs(100)/oxide and GaAs(100)/ZnSe interface (1991)

    Notes: A series of subpicosecond time-resolved reflectivity measurements on n-type GaAs(100) interfaces at photoexcitation densities of 1018 cm−3 is reported. It is observed that the temporal dependence of the reflectivity signal within the first several picoseconds following photoexcitation is highly dependent upon interface preparation. The surface of the GaAs was prepared in several ways: by the growth of a thermal oxide overlayer, a photochemically passivated oxide overlayer, and an epitaxial ZnSe overlayer.

    Diffusion of silver in C60 thin films (1993)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 63 (1993), S. 2438-2440

    Topics: Physics
    Notes: The diffusion of silver atoms into C60 solid thin films is observed. The diffusion process is significant at temperatures just above room temperature, with an activation energy of 2.5±0.5 eV (60 kcal/mol). Temperature dependent conductivity measurements indicate that silver atoms form an impurity band in solid C60 with an activation energy of 0.26 eV. The ready interdiffusion of silver and C60 may have important implications in the formation of C60/metal contacts or C60/metal layered structures or materials.

    Effects of photo-oxidation on conjugated polymer films (1997)

    Notes: We have used two-photon photoemission as a sensitive monitor of the effects of photo-oxidation on poly[2-methoxy,5-(2′-ethylhexoxy)-1,4-phenylenevinylene] films. We observe a downward shift in the triplet exciton energy as well as a dramatic narrowing of the triplet exciton photoemission linewidth as photo-oxidation progresses. Both of these effects are attributed to changes in the physical and electronic structure of the film due to carbonyl defect formation on the polymer chains. This technique provides a highly sensitive probe of photo-oxidation which may be useful in the optimization of conjugated-polymer-based devices and displays. © 1997 American Institute of Physics.

    Infrared extinction properties of gold nanoshells (1999)

    Notes: Gold nanoshells, nanoparticles consisting of a silica core coated with a thin gold shell, exhibit a strong optical resonance that depends sensitively on their core radius and shell thickness. Gold nanoshells have been fabricated with a peak optical extinction that can be varied across the near-infrared region of the spectrum (800 nm–2.2 μm). Multipolar plasmon resonances are clearly resolvable in the extinction spectra and agree well with electromagnetic theory. Additional resonances due to particle aggregation are also observed. The frequency agile infrared properties of these nanoparticles make them particularly attractive for a range of technologically important applications. © 1999 American Institute of Physics.

    Light scattering from dipole and quadrupole nanoshell antennas (1999)

    Notes: Metal nanoshells are nanoscale optical components that allow for the controllable redirection of electromagnetic radiation via careful engineering of their multilayer structures. By varying the core size and shell thickness of these nanoparticles, nanoscale "antennas" are constructed that can be selectively driven into a dipolar or quadrupolar oscillation pattern. With scattering cross sections many times larger than their physical cross section, these antennas efficiently couple to the incident electromagnetic wave. These structures can focus, redirect, or split the incident light with subwavelength precision, and may find useful applications in the remote coupling of electromagnetic signals into nanoscale machines or devices. © 1999 American Institute of Physics.

    Excimer-laser-induced electric conductivity in thin-film C60 (1993)

    Notes: Abstract The electrical conductivity of thin-film C60 has been changed by more than seven orders of magnitude with KrF (248nm) excimer-laser irradiation. Specific conductivities of 1 Ω−1 · cm−1 have been obtained. The onset of conductivity is consistent with a laser-induced metal-insulator phase transition. The threshold for KrF-laser ablation of C60 has been determined to be 20±2 mJ/cm2. This laser-induced process generates an all-carbon semiconductor-metallic junction which may have important technological applications.
