Journal ArticleDOI
Raman-scattering and transmission-electron-microscopy studies of fluorine-intercalated graphite fibers CxF (7.8 >= x >= 2.9).

TL;DR: Lattice fringe images of fluorine-intercalated graphite fibers show wavy fringes, and the waviness is identified with semi-ionic (covalent) bonding, and these Raman results are consistent with high-resolution TEM experiments on the same fibers.
Journal ArticleDOI
Characterization of Activated Carbon Fibers
TL;DR: In this article, low-temperature electrical conductivity and Raman scattering were used as characterization tools for activated carbon fibers, which have a high density of defects and a huge specific surface area.
Journal ArticleDOI
ab-plane optical properties of YBa2Cu3O7- delta Bry single crystals.
Yiqin Wang,A. M. Rao,J.-G. Zhang,Xiang-Xin Bi,P. C. Eklund,M. S. Dresselhaus,P. P. Nguyen,Jagadeesh S. Moodera,G. Dresselhaus,Harry B. Radousky,R.S. Glass,M. J. Fluss,J. Z. Liu +12 more
TL;DR: In this article, room-temperature infrared and optical-spectroscopic measurements are reported on brominated single-crystal samples and phonon frequency softening is observed for the 591-${\mathrm{cm}}^{\mathm{\ensuremath{-}}1}$ phonon [Cu(2)-O(2) in-plane stretch] mode.
Journal ArticleDOI
Vibrational Modes in C60 and C60 Polymer
P. C. Eklund,A. M. Rao,Ping Zhou,Ying Wang,K. A. Wang,J. M. Holden,M. S. Dresselhaus,G. Dresselhaus +7 more
TL;DR: The vibrational properties of oxygen-free C60 films indicate the nearly ideal molecular nature of solid C60 and the formation of covalent C-C bonds between C60 molecules in the polymeric phase.
Journal ArticleDOI
Raman Studies of Fluorine-Intercalated Carbon Fibers
TL;DR: In this article, Raman scattering measurements on fluorine-intercalated graphite fibers (CχF) for stoichiometries χ = 7.8, 4.5 and 2.9 were performed.
