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…

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…
