Single-crystal elastic moduli, anisotropy and the B1-B2 phase transition of NaCl at high pressures: Experiment vs. ab-initio calculations
Feng Xu, Laurent Belliard, Chenhui Li +5
Single-crystal elastic moduli, Cij, and the B1-B2 phase transition of NaCl were investigated experimentally, using time-domain Brillouin scattering (TDBS), and theoretically, via d…
Elastic and magnetoelastic properties of TbMnO3 single crystal by nanosecond time resolved acoustics and first-principles calculations
Pierre Hemme, Philippe Djemia, Pauline Rovillain +8
Time resolved pump and probe acoustics and first-principles calculations were employed to assess elastic properties of the TbMnO3 perovskite manganite having orthorhombic symmetry.…
Elastic properties assessment in the multiferroic BiFeO3 by pump and probe method
Pierre Hemme, Philippe Djemia, Pauline Rovillain +8
We have performed elasticity measurements in the bulk multiferroic BiFeO3 (BFO) using acoustical pump and probe spectroscopy. The sound velocities of the (quasi)-longitudinal and o…
Effect of ion-implantation-induced defects and Mg dopants on thermoelectric properties of ScN
Nina Tureson, Marc Marteau, Thierry Cabioch +10
For applications in energy harvesting, environmentally friendly cooling, and as power sources in remote or portable applications, it is desired to enhance the efficiency of thermoe…
Spatio-Temporal Imaging of the Acoustic Field Emitted by a Single Copper Nanowire Copper Nanowires Fabrication
Cyril Jean, Laurent Belliard, Thomas W. Cornelius +5
The monochromatic and geometrically anisotropic acoustic field generated by 400 nm and 120 nm diameter copper nanowires simply dropped on a 10 m silicon membrane is investigated…
Backward Propagating Acoustic Waves in Single Gold Nanobeams
Cyril Jean, Laurent Belliard, Loïc Becerra +1
Femtosecond pump-probe spectroscopy has been carried out on suspended gold nanostructures with a rectangular cross section lithographed on a silicon substrate. With a thickness fix…
Direct Observation of Propagating Gigahertz Coherent Guided Acoustic Phonons in Free Standing Single Copper Nanowires
Cyril Jean, Laurent Belliard, Thomas W. Cornelius +5
We report on gigahertz acoustic phonon waveguiding in free-standing single copper nanowires studied by femtosecond transient reflectivity measurements. The results are discussed on…
