Optically-Controlled Nano-Transducers Based on Cleaved Superlattices for Monitoring Gigahertz Surface Acoustic Vibrations
Changxiu Li, Nikolay Chigarev, Théo Thréard +6
Surface acoustic waves (SAWs) convey energy at subwavelength depths along surfaces. Using interdigital transducers (IDTs) and opto-acousto-optic transducers (OAOTs), researchers ha…
Time-domain Brillouin scattering theory for probe light and acoustic beams propagating at an angle and acousto-optic interaction at material interfaces
Vitalyi E. Gusev, Théo Thréard, David H. Hurley +1
A theory has been developed to interpret time-domain Brillouin scattering (TDBS) experiments involving coherent acoustic pulse (CAP) and light pulse beams propagating at an angle t…
Non-thermal transport of energy driven by photoexcited carriers in switchable solid states of GeTe
R. Gu, T. Perrault, V. Juvé +10
Phase change alloys have seen widespread use from rewritable optical discs to the present day interest in their use in emerging neuromorphic computing architectures. In spite of th…
3D characterisation of individual grains of coexisting high-pressure H2O ice phases by time-domain Brillouin scattering
Sathyan Sandeep, Théo Thréard, Elton De Lima Savi +6
Time-domain Brillouin scattering uses ultrashort laser pulses to generate coherent acoustic pulses of picoseconds duration in a solid sample and to follow their propagation in orde…
Ultrafast light-induced shear strain probed by time-resolved X-ray diffraction: the model multiferroic BiFeO as a case study
V. Juvé, R. Gu, S. Gable +12
Enabling the light-control of complex systems on ultra-short timescales gives rise to rich physics with promising applications. While crucial, the quantitative determination of bot…
Growing Phenotype-controlled Phononic Materials from Plant Cells Scaffolds
Maroun Abi Ghanem, Liliane Khoryati, Reza Behrou +5
Biological composites offer self-healing properties, biocompatibility, high responsivity to external stimuli, and multifunctionality, due, in part, to their complex, hierarchical m…
Investigation of interfacial stiffnesses of a tri-layer using Zero-Group Velocity Lamb modes
Sylvain Mezil, François Bruno, Samuel Raetz +3
Zero-Group Velocity (ZGV) Lamb waves are studied in a structure composed of two plates bonded by an adhesive layer. The dispersion curves are calculated for a Duralumin/epoxy/Dural…
