The fate of optical excitons in FAPbI3 nanocube superlattices
Alessandra Milloch, Umberto Filippi, Paolo Franceschini +8
Understanding the nature of the photoexcitation and ultrafast charge dynamics pathways in organic halide perovskite nanocubes and their aggregation into superlattices is key for th…
Temperonic Crystal: a superlattice for temperature waves in graphene
Marco Gandolfi, Claudio Giannetti, Francesco Banfi
The temperonic crystal, a periodic structure with a unit cell made of two slabs sustaining temperature wave-like oscillations on short time-scales, is introduced. The complex-value…
Accessing temperature waves: a dispersion relation perspective
Marco Gandolfi, Giulio Benetti, Christ Glorieux +2
In order to account for non-Fourier heat transport, occurring on short time and length scales, the often-praised Dual-Phase-Lag (DPL) model was conceived, introducing a causality r…
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…
