Contribution of the buffer layer to the Raman spectrum of epitaxial graphene on SiC(0001)

F. Fromm, M.H. Oliveira, A. Molina-Sanchez, M. Hundhausen, J.M.J. Lopes, H. Riechert, L. Wirtz, T. Seyller

We report a Raman study of the so-called buffer layer with (6√3 × 6√3)R30◦ periodicity which forms the intrinsic interface structure between epitaxial graphene and SiC(0001). We show that this interface structure leads to a nonvanishing signal in the Raman spectrum at frequencies in the range of…

As the power of electronic systems powers is increasing, thermal fluxes are getting higher, up to more than 100W/cm2 in more critical cases. They result in hot spots with various consequences, especially performance reduction and reliability issues. Most of the prior research has been focused on…

Coupled transport and poro-mechanical properties of a heat-treated mortar under confinement

Xiao-Ting Chen, Grégory Caratini, Catherine A. Davy, David Troadec, Frédéric Skoczylas

This experimental investigation focuses on a mortar heated/cooled up to 105, 200, 300 or 400 °C. The reference state for the material corresponds to mass stabilization at 60 °C oven-drying. Extensive (and tortuous) micro-crack development is shown by SEM and FIB/SEM imaging after heating-cooling up…
