Nonlocal study of the near field radiative heat transfer between two n-doped semiconductors
F. Singer, Y. Ezzahri, Karl Joulain
We study in this work the near-field radiative heat transfer between two semi-infinite parallel planes of highly n-doped semiconductors. Using a nonlocal model of the dielectric pe…
Modulation and amplification of radiative far field heat transfer: Towards a simple radiative thermal transistor
Karl Joulain, Younès Ezzahri, Jérémie Drevillon +1
We show in this article that phase change materials (PCM) exhibiting a phase transition between a dielectric state and a metallic state are good candidates to perform modulation as…
Dynamical lattice thermal conductivity, Shastry sum rule and second sound in bulk semiconductor crystals
Younes Ezzahri, Karl Joulain
The paper discusses the fundamental behavior of the dynamical lattice thermal conductivity k(W) of bulk cubic semiconductor crystals. The calculation approach is based on solving B…
Heat transfer between a nano-tip and a surface
Pierre-Olivier Chapuis, Jean-Jacques Greffet, Karl Joulain +1
We study quasi-ballistic heat transfer through air between a hot nanometer-scale tip and a sample. The hot tip/surface configuration is widely used to perform nonintrusive confined…
