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…
Thermoelectric transport properties of silicon: Towards an ab initio approach
Z. Wang, S. Wang, S. Obukhov +4
We have combined the Boltzmann transport equation with an {\it ab initio} approach to compute the thermoelectric coefficients of semiconductors. Electron-phonon, ionized impurity,…
Breakdown of Herring's processes in cubic semiconductors for sub-terahertz longitudinal acoustic phonons
Maxime Markov, Jelena Sjakste, Nathalie Vast +3
In the present work we explain the anomalous behavior of the attenuation of the longitudinal acoustic phonon in GaAs as a function of the phonon energy in the sub-THz domain. T…
Ultrafast electrons dynamics reveal the high potential of InSe for hot carrier optoelectronics
Zhesheng Chen, Christine Giorgetti, Jelena Sjakste +9
We monitor the dynamics of hot carriers in InSe by means of two photons photoelectron spectroscopy (2PPE). The electrons excited by photons of 3.12 eV experience a manifold relaxat…
