Far- and near-field photon noise limits to the detectivity of nanometer-thick thermal detectors
Olivier Merchiers, Aapo Varpula, Kirsi Tappura +2
Thermal-radiation detectors such as bolometers -- often found as thin, suspended films -- are intrinsically limited by their optical absorption properties and by their intrinsic th…
Performances of far and near-field thermophotonic refrigeration devices from the detailed-balance approach
Thomas Châtelet, Julien Legendre, Olivier Merchiers +1
We study a near-field thermophotonic (NF-TPX) refrigerating device, consisting of a lightemitting diode and a photovoltaic cell in close proximity. Calculations are performed in th…
Thermal Radiation at the Nanoscale and Applications
Pierre-Olivier Chapuis, Bong Jae Lee, Alejandro Rodriguez
There has been a paradigm shift from the well-known laws of thermal radiation derived over a century ago, valid only when the length scales involved are much larger than the therma…
Operating conditions and thermodynamic bounds of dual radiative heat engines
Julien Legendre, Pierre-Olivier Chapuis
We propose a unified description of dual radiative heat engines (RHEs), consisting of two facing optoelectronic components (diodes) and capable of generating electrical power from…
Phonon-blocked junction refrigerators for cryogenic quantum devices
E. Mykkänen, J. S. Lehtinen, A. Ronzani +4
Refrigeration is an important enabler for quantum technology. The very low energy of the fundamental excitations typically utilized in quantum technology devices and systems requir…
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…
