Analysis of periodic Mo/Si multilayers: influence of the Mo thickness
H. Maury, Jean-Michel André, Karine Le Guen +6
A set of Mo/Si periodic multilayers is studied by non destructive analysis methods. The thickness of the Si layers is 5 nm while the thickness of the Mo layers changes from one mul…
Hidden polymorphs drive the vitrification in B2O3
Guillaume Ferlat, Ari Paavo Seitsonen, Michele Lazzeri +1
Understanding the conditions which favor crystallisation or vitrification of liquids has been a long-standing scientific problem. Another connected, and not yet well understood que…
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…
Temperature evolution of infrared- and Raman-active phonons in graphite
P. Giura, N. Bonini, G. Creff +3
We perform a comparative experimental and theoretical study of the temperature dependence up to 700 K of the frequency and linewidths of the graphite E1u and E2g optical phonons (~…
Spectroscopic study of double-walled carbon nanotubes functionalization for preparation of carbon nanotube / epoxy composites
Vincent Leon, Romain Parret, Robert Almairac +7
A spectroscopic study of the amino functionalization of double-walled carbon nanotube (DWCNT) is performed. Original experimental investigations by near edge X-ray absorption fine…
Micro-Brillouin spectroscopy mapping of the residual density field induced by Vickers indentation in a soda-lime silicate glass
H. Tran, S. Clément, R. Vialla +2
High-resolution Brillouin scattering is used to achieve 3-dimensional maps of the longitudinal acoustic mode frequency shift in soda-lime silicate glasses subject to Vickers indent…
