ABSTRACT
Iodine-doped multiwall carbon nanotubes (I-MWNTs) were characterized by means of Raman scattering and thermogravimetric analysis. The results show that multiwall carbon nanotubes (MWNTs) can be effectively doped by iodine and exchange electrons with iodine. Iodine atoms form charged polyiodide chains inside tubes of different inner diameter, which is similar to the iodine-doped single-wall carbon nanotubes (I-SWNTs), but can not intercalate into the graphene walls of MWNTs. The Raman scattering behavior of I-MWNTs exhibits some differences from that of I-SWNTs and the low-dimensional conductive hydrocarbon-iodine complex “perylene·I[sub 2.92].” © 2002 American Institute of Physics.

    The intensity of resonance Raman lines, the radial breathing mode (RBM) and the G-band of single wall carbon nanotubes (SWNTs) are found to display anomalous non-linear changes when laser power or accumulation time are changed. The intensity of the D-band on the other hand is found to behave in...

    Photoselective resonance Raman scattering is well known for C[sub60] pristine SWNTs and has been extensively studied. In this contribution we present a detailed study of the photoselective resonance Raman scattering for C[sub60] encapsulated in single wall carbon nanotubes (SWNTs), so-called...

    Polarized Raman spectra are measured for 0.4 nm single-walled carbon nanotubes embedded in the zeolite matrix. The polarization dependence of the Raman intensity of the radial breathing mode showed that the carbon nanotubes inside the channels of the zeolite are perfectly aligned. The observed...

    The temperature-dependent frequency shift of resonant Raman spectra of double-wall carbon nanotubes is investigated in the range of 78-650 K.

    The Raman spectroscopy is one of the most used tools for the experimental characterisation of the atomic structure of bundles of single-wall carbon nanotubes. More particularly, the low frequency range (150 – 200 cm[sup -1]) is dominated by the signature of the resonant fully radial...

    We present a new interpretation of the origin of the first-order Raman modes in single-wall carbon nanotubes. Similar to the disorder-induced D mode, the high-energy modes are determined by double-resonant scattering. Our model predicts an excitation-energy dependence of the Raman frequencies,...
