“…Indeed, the observed Br-C distance is close to the sum of bromine ionic and carbon van der Waals radii, leading to possible weak chemical bonding and charge transfer between these atoms, which could explain the chemical shifts detected for the CuBr@SWNT and the AgBr@SWNT by a number of methods including Raman scattering, XPS, XES, XANES, LEED, etc. (Kleimenov, Eliseev & Vinogradov, 2009;Eliseev et al, 2010).…”

SummaryNanocomposites consisting of one-dimensional (1D) crystals of the cationic conductors CuI, CuBr and AgBr inside singlewalled carbon nanotubes, mainly (n, 0), were obtained using the capillary technique. 1D crystal structure models were proposed based on the high resolution transmission electron microscopy performed on a FEI Titan 80-300 at 80 kV with aberration correction. According to the models and image simulations there are two modifications of 1D crystal: hexagonal close-packed bromine (iodine) anion sublattice (growth direction <001>) and 1D crystal cubic structure (growth direction <112>) compressed transversely to the nanotube (D m ∼1.33 nm) axis. Tentatively this kind of 1D crystal can be considered as monoclinic. One modification of the anion sublattice reversibly transforms into the other inside the nanotube, probably initiated by electron beam heating. As demonstrated by micrographs, copper or silver cations can occupy octahedral positions or are statistically distributed across two tetrahedral positions. A 1DAgBr@SWNT (18, 0; 19, 0) pseudoperiodic 'lattice distortion' is revealed resulting from convolution of the nanotube wall function image with 1D cubic crystal function image.

“…In our opinion the extension to electrochemically gated extreme nanowires 20 at temperatures down to 4 K 36 , allowing measurements on nanowires over a wide range of charge densities will be key to understanding these materials. Finally using Raman scattering to understanding structural and melting transitions of extreme nanowires may help to optimize the quality of the samples that can be produced even further.…”

“…Whilst it still to be proven, it is likely that in some magnetic extreme nanowires spin excitations will lead to Raman scattering allowing them to be probed. Extension of Raman scattering to samples held in a spectroelectrochemical cell can be used to probe charge transfer between extreme nanowires and host nanotubes 20 . As a characterization tool Raman spectroscopy provides a method for non-contact, non-destructive determination of nanowire type and quality 21 .…”

This paper briefly describes how nanowires with diameters corresponding to 1 to 5 atoms can be produced by melting a range of inorganic solids in the presence of carbon nanotubes. These nanowires are extreme in the sense that they are the limit of miniaturization of nanowires and their behavior is not always a simple extrapolation of the behavior of larger nanowires as their diameter decreases. The paper then describes the methods required to obtain Raman spectra from extreme nanowires and the fact that due to the van Hove singularities that 1D systems exhibit in their optical density of states, that determining the correct choice of photon excitation energy is critical. It describes the techniques required to determine the photon energy dependence of the resonances observed in Raman spectroscopy of 1D systems and in particular how to obtain measurements of Raman cross-sections with better than 8% noise and measure the variation in the resonance as a function of sample temperature. The paper describes the importance of ensuring that the Raman scattering is linearly proportional to the intensity of the laser excitation intensity. It also describes how to use the polarization dependence of the Raman scattering to separate Raman scattering of the encapsulated 1D systems from those of other extraneous components in any sample.
