A new regime of nanoscale thermal transport: collective diffusion counteracts dissipation inefficiency
Kathleen M. Hoogeboom-Pot, Jorge N. Hernandez-Charpak, Erik H. Anderson +5
Understanding thermal transport from nanoscale heat sources is important for a fundamental description of energy flow in materials, as well as for many technological applications i…
Design of a surface acoustic wave mass sensor in the 100 GHz range
Damiano Nardi, Elisa Zagato, Gabriele Ferrini +2
A design for photoacoustic mass sensors operating above 100 GHz is proposed. The design is based on impulsive optical excitation of a pseudosurface acoustic wave in a surface phono…
Ab-initio calculation of all-optical time-resolved calorimetry of nanosized systems: Evidence of nanosecond-decoupling of electron and phonon temperatures
F. Banfi, F. Pressacco, B. Revaz +4
The thermal dynamics induced by ultrashort laser pulses in nanoscale systems, i.e. all-optical time-resolved nanocalorimetry is theoretically investigated from 300 to 1.5 K. We rep…
Ultrafast laser pulses to detect and generate fast thermo-mechanical transients in matter
C. Giannetti, F. Banfi, D. Nardi +2
The use of femtosecond laser pulses to impulsively excite thermal and mechanical transients in matter has led, in the last years, to the development of picosecond acoustics. Recent…
Pseudo-surface acoustic waves in hypersonic surface phononic crystals
D. Nardi, F. Banfi, C. Giannetti +3
We present a theoretical framework allowing to properly address the nature of surface-like eigenmodes in a hypersonic surface phononic crystal, a composite structure made of period…
