Impact of roughness on heat conduction involving nanocontacts
Eloïse Guen, Pierre-Olivier Chapuis, Nupinder Jeet Kaur +2
The impact of surface roughness on conductive heat transfer across nanoscale contacts is investigated by means of scanning thermal microscopy. Silicon surfaces with out-of-plane rm…
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…
GaAs-Based Near-Field Thermophotonic Devices: Approaching The Idealized Case With One-Dimensional PN Junctions
Julien Legendre, Pierre-Olivier Chapuis
Thermophotonics (TPX) is a technology close to thermophotovoltaics (TPV), where a heated light-emitting diode (LED) is used as the active thermal emitter of the system. It allows t…
