Overcoming non-radiative losses with AlGaAs PIN junctions for near-field thermophotonic energy harvesting
Julien Legendre, Pierre-Olivier Chapuis
In a thermophotonic device used in an energy-harvesting configuration, a hot light-emitting diode (LED) is coupled to a photovoltaic (PV) cell by means of electroluminescent radiat…
Temperature dependence of near-field radiative heat transfer above room temperature
Christophe Lucchesi, Rodolphe Vaillon, Pierre-Olivier Chapuis
Stefan-Boltzmann's law indicates that far-field blackbody radiation scales at the fourth power of temperature. The temperature dependence of radiative heat transfer in the near fie…
Increase of Thermal Resistance Between a Nanostructure and a Surface due to Phonon Multireflections
S. Volz, P. -O. Chapuis
The thermal resistance between a nanostructure and a half-body is calculated in the framework of particle-phonons physics. The current models approximate the nanostructure as a the…
Temperature measurement of sub-micrometric ICs by scanning thermal microscopy
S. Gomès, Po Chapuis, F. Nepveu +7
Surface temperature measurements were performed with a Scanning Thermal Microscope mounted with a thermoresistive wire probe of micrometrSurface temperature measurements were perfo…
