Phonon dispersion and low energy anomaly in CaC
Matteo D'Astuto, Matteo Calandra, N. Bendiab +10
We report measurements of phonon dispersion in CaC using inelastic X-ray and neutron scattering. We find good overall agreement, particularly in the 50 meV energy region, betwe…
How the hydrogen bond in NHF is revealed with Compton scattering
B. Barbiellini, Ch. Bellin, G. Loupias +2
In order to probe electron wave functions involved in the bonding of NHF, we have performed Compton scattering experiments in an oriented single crystal and in a powder. Ab ini…
Pressure-induced order-disorder phase transition in superconducting CaC6
A. Gauzzi, N. Bendiab, M. d'Astuto +9
By means of synchrotron X-ray diffraction, we studied the effect of high pressure, P, up to 13 GPa on the room temperature crystal structure of superconducting CaC6. In this P rang…
Scanning Tunneling Spectroscopy on the novel superconductor CaC6
N. Bergeal, V. Dubost, Y. Noat +7
We present scanning tunneling microscopy and spectroscopy of the newly discovered superconductor CaC. The tunneling conductance spectra, measured between 3 K and 15 K, show a c…
Pressure-induced enhancement of superconductivity and superconducting-superconducting transition in CaC
Andrea Gauzzi, S. Takashima, N. Takeshita +6
We measured the electrical resistivity, , of superconducting CaC at ambient and high pressure up to 16 GPa. For 8 GPa, we found a large increase of …
Superconductivity in Li3Ca2C6 intercalated graphite
Nicolas Emery, Claire Herold, Jean-Francois Mareche +3
In this letter, we report the discovery of superconductivity in Li3Ca2C6. Several graphite intercalation compounds (GICs) with electron donors, are well known as superconductors. I…
