Wideband Mid Infrared Absorber using surface Doped Black Silicon
Sreyash Sarkar, Elyes Nefzaoui, Georges Hamaoui +3
Black silicon (BSi) is a synthetic nanomaterial with high aspect ratio nano protrusions inducing several interesting properties such as a very large absorptivity of incident radiat…
Far-Field Radiative Thermal Rectification with Bulk Materials
Sreyash Sarkar, Elyes Nefzaoui, Philippe Basset +1
In this paper, we explore the far-field radiative thermal rectification potential of common materials such as metals, dielectrics and doped semi-conductors using radiative and ther…
Sensitivity optimization of micro-machined thermo-resistive flow-rate sensors on silicon substrates
Shaun Ferdous, Sreyash Sarkar, Frederic Marty +4
We report on an optimized micro-machined thermal flow-rate sensor as part of an autonomous multi-parameter sensing device for water network monitoring. The sensor has been optimize…
Radiative thermal rectification using superconducting materials
Elyes Nefzaoui, Karl Joulain, Jérémie Drevillon +1
Thermal rectification phenomenon is a manifestation of an asymmetry in the heat flux when the temperature difference between two interacting thermal reservoirs is reversed. In this…
A simple radiative thermal diode
Elyes Nefzaoui, Jérémie Drevillon, Younès Ezzahri +1
We present a thermal rectification device concept based on far-field radiative exchange between two selective emitters. Rectification is achieved due to the fact that one of the se…
Maximal near-field radiative heat transfer between two plates
Elyes Nefzaoui, Younès Ezzahri, Jérémie Drevillon +1
A parametric study of Drude and Lorentz models performances in maximizing near-field radiative heat transfer between two semi-infinite planes separated by nanometric distances at r…
Selective emitters design and optimization for thermophotovoltaic applications
Elyes Nefzaoui, Jérémie Drevillon, Karl Joulain
Among several solutions to exploit solar energy, thermophotovoltaics (TPV) have been popularized and have known great breakthroughs during the past two decades. Yet, existing syste…
Impact of a Liquid Drop on a Granular Medium: inertia, viscosity and surface tension effects on the drop deformation
Elyes Nefzaoui, Olivier Skurtys
An experimental study of liquid drop impacts on a granular medium is proposed. Four fluids were used to vary physical properties: pure distilled water, water with glycerol at 2 con…
