Isostructural phase transition and equation of state of type-I and type-VIII metallic sodium borosilicide clathrates
M. Demoucron, S. Pandolfi, Y. Guarnelli +10
Electronic properties of silicon-based clathrates can be tuned by boron incorporation into the silicon cage network. Sodium borosilicides clathrate outstands with uncommon stoichio…
Phonon-polaritons in Zn(1-x)MgxTe (x<0.09): A Raman scattering study
D. Singh, A. Elmahjoubi, O. Pages +10
Phonon-polaritons (PP) are phonon-photon coupled modes. Using near-forward Raman scattering, the PP of the cubic Zn(1-x)MgxTe (x<0.09) semiconductor alloy could be measured. While…
Boron carbide under torsional deformation: evidence of the formation of chain vacancies in the plastic regime
Amrita Chakraborti, Antoine Jay, Olivier Hardouin Duparc +4
We report a combined experimental and theoretical study of boron carbide under stress/deformation. A special rotating anvil press, the rotating tomography Paris Edinburgh cell (Rot…
Synthesis of boron carbide from its elements up to 13 GPa
Amrita Chakraborti, Nicolas Guignot, Nathalie Vast +1
The formation of boron carbide under high pressures and from elemental reactants has been studied and optimum parameters have been determined by varying the (P, T, reactants) condi…
Phase boundary between Na-Si clathrates of structures I and II at high pressures and high temperatures
Zied Jouini, Oleksandr O. Kurakevych, Hicham Moutaabbid +3
Understanding the covalent clathrate formation is a crucial point for the design of new superhard materials with intrinsic coupling of superhardness and metallic conductivity. Sili…
Boron phosphide under pressure: in situ study by Raman scattering and X-ray diffraction
Vladimir L. Solozhenko, Oleksandr O. Kurakevych, Yann Le Godec +2
Cubic boron phosphide BP has been studied in situ by X-ray diffraction and Raman scattering up to 55 GPa at 300 K in a diamond anvil cell. The bulk modulus of B0 = 174(2) GPa has b…
Phonon study of rhombohedral BS under high pressure
Kirill A. Cherednichenko, Petr S. Sokolov, Aleksandr Kalinko +4
Raman spectra of rhombohedral boron monosulfide (r-BS) were measured under pressures up to 34 GPa at room temperature. No pressure-induced structural phase transition was observed,…
Effect of nanostructuration on compressibility of cubic BN
Y. Le Godec, O. O. Kurakevych, P. Munsch +3
Compressibility of high-purity nanostructured cBN has been studied under quasi-hydrostatic conditions at 300 K up to 35 GPa using diamond anvil cell and angle-dispersive synchrotro…
