Thermal transport from 1D- and 2D-confined nanostructures on silicon probed using coherent extreme UV light: General and predictive model yields new understanding
Albert Beardo, Joshua L. Knobloch, Lluc Sendra +9
Heat management is crucial in the design of nanoscale devices as the operating temperature determines their efficiency and lifetime. Past experimental and theoretical works explori…
Observation of second sound in a rapidly varying temperature field in Ge
Albert Beardo, Miquel López-Suárez, Luis Alberto Pérez +9
Second sound is known as the thermal transport regime where heat is carried by temperature waves. Its experimental observation was previously restricted to a small number of materi…
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…
A slip-based model for the size-dependent effective thermal conductivity of nanowires
M. Calvo-Schwarzwälder, M. G. Hennessy, P. Torres +2
The heat flux across a nanowire is computed based on the Guyer-Krumhansl equation. Slip conditions with a slip length depending on both temperature and nanowire radius are introduc…
First principles Kinetic-Collective thermal conductivity of semiconductors
P. Torres, A. Torello, J. Bafaluy +3
A fully predictive Kinetic Collective Model using first principles phonon spectra and relaxation times is presented. Thermal conductivity values obtained for Si, Ge, C (diamond) an…
Thermal conductivity of group-IV Semiconductors from a Kinetic-Collective Model
C. de Tomas, A. Cantarero, A. F. Lopeandia +1
The thermal conductivity of several diamond-like materials is calculated from a kinetic-collective model. From this approach, a thermal conductivity expression is obtained that inc…
From kinetic to collective behavior in thermal transport on semiconductors and semiconductor nanostructures
C. de Tomas, A. Cantarero, A. F. Lopeandia +1
We present a model which deepens into the role that normal scattering has on the thermal conductivity in semiconductor bulk, micro and nanoscale samples. Thermal conductivity as a…
