Anisotropy in the dielectric function of BiTe from first principles: From the UV-visible to the infrared range
R. Busselez, A. Levchuk, P. Ruello +2
The dielectric properties of BiTe, a layered compound crystallizing in a rhombohedral structure, are investigated by means of first-principles calculations at the random ph…
Direct observation of electron thermalization and electron-phonon coupling in photoexcited bismuth
J. Faure, J. Mauchain, E. Papalazarou +7
We investigate the ultrafast response of the bismuth (111) surface by means of time resolved photoemission spectroscopy. The direct visualization of the electronic structure allows…
Observation of large multiple scattering effects in ultrafast electron diffraction on single crystal silicon
I. Gonzalez Vallejo, G. Gallé, B. Arnaud +8
We report on ultrafast electron diffraction on high quality single crystal silicon. The ultrafast dynamics of the Bragg peaks exhibits a giant photo-induced response which can only…
Anisotropic thermal expansion of bismuth from first principles
B. Arnaud, S. Lebègue, G. Raffy
Some anisotropy in both mechanical and thermodynamical properties of bismuth is expected. A combination of density functional theory total energy calculations and density functiona…
