Intercalate Phonon Densities of States for Alkali-Graphite Compounds


Neutron scattering methods have been used to determine the partial phonon densities of states gM(ν) for in-plane vibrations of M atoms in MCx compounds, where M = K, Rb or Cs, and x = 8, 24, 36. Only modes with both phonon wave vectors and displacements in the basal plane are represented in gM(ν). Detailed measurements of the temperature dependence were made for RbC24 and KC24, in order to study the influence of the order-disorder transformations in these compounds. The results are interpreted in terms of different pictures of the disordered state.
