Descriptors of intrinsic hydrodynamic thermal transport: screening a phonon database in a machine learning approach
Pol Torres, Stephen Wu, Shenghong Ju +4
Machine learning techniques are used to explore the intrinsic origins of the hydrodynamic thermal transport and to find new materials interesting for science and engineering. The h…
Giant electrophononic response in PbTiO by strain engineering
Pol Torres, Jorge Íñiguez, Riccardo Rurali
We demonstrate theoretically how, by imposing epitaxial strain in a ferroelectric perovskite, it is possible to achieve a dynamical control of phonon propagation by means of extern…
Thermal conductivity and phonon hydrodynamics in transition metal dichalcogenides from first-principles
Pol Torres, Francesc Xavier Alvarez, Xavier Cartoixà +1
We carry out a systematic study of the thermal conductivity of four single-layer transition metal dichalcogenides, MX (M = Mo, W; X = S, Se) from first-principles by solving th…
Effective thermal conductivity of rectangular nanowires based on phonon hydrodynamics
Marc Calvo-Schwarzwälder, Matthew G. Hennessy, Pol Torres +2
A mathematical model is presented for thermal transport in nanowires with rectangular cross sections. Expressions for the effective thermal conductivity of the nanowire across a ra…
Thermal conductivity of bulk and nanoscaled Si/Ge alloys from the Kinetic Collective Model
P. Torres, C. de Tomas, A. Lopeandia +2
Several hitherto unexplained features of thermal conductivity in group IV materials, such as the change in the slope as a function of sample size for pure vs. alloyed samples and t…
