Lattice dynamics of the cluster chain compounds M2Mo6Se6
Liam Gannon, Lilia Boeri, Christopher A. Howard +6
The lattice dynamics of members of the M2Mo6Se6 family of materials with guest ions M = K, Rb, Cs, In, and Tl has been studied using inelastic x-ray scattering and Raman spectrosco…
Superconductivity in Ca-doped graphene
J. Chapman, Y. Su, C. A. Howard +6
Graphene, a zero-gap semimetal, can be transformed into a metallic, semiconducting or insulating state by either physical or chemical modification. Superconductivity is conspicuous…
Superconductivity in graphite intercalation compounds
Robert P. Smith, Thomas E. Weller, Christopher A. Howard +4
The field of superconductivity in the class of materials known as graphite intercalation compounds has a history dating back to the 1960s. This paper recontextualizes the field in…
Comparative study of the phonons in non-superconducting BaC6 and superconducting CaC6 using inelastic x-ray scattering
A. C. Walters, C. A. Howard, M. H. Upton +8
The low energy phonons of two different graphite intercalation compounds (GICs) have been measured as a function of temperature using inelastic x-ray scattering (IXS). In the case…
Neutron scattering study of the high energy graphitic phonons in superconducting CaC
M. P. M. Dean, A. C. Walters, C. A. Howard +7
We present the results of a neutron scattering study of the high energy phonons in the superconducting graphite intercalation compound CaC. The study was designed to address hi…
Anisotropic Electron-Phonon Coupling and Dynamical Nesting on the Graphene Sheets in CaC6
T. Valla, J. Camacho, Z-H. Pan +4
Superconductivity in graphite intercalated compounds has been studied for more than 40 years and it is still not fully understood, despite the recent progress and the discovery of…
