Radiative Thermal Memristor
Résumé
Based on the thermal hysteresis of a phase change material exchanging
radiative heat with a phase invariable one, we propose a radiative
thermal memristor characterized by a Lissajous curve between their
exchanged heat flux and temperature difference periodically modulated in
time. For a memristor with terminals of VO2 and a blackbody, it is shown
that (i) the temperature variations of its memristance follow a closed
loop determined by the thermal hysteresis width of VO2, and (ii) the
thermal memristance on-off ratio is determined by the contrast of VO2
emissivities for its insulating and metallic phases and is equal to 3.6.
The analogy of the proposed memristor to its electrical counterpart
makes it promising to lay the foundations of the thermal computing with
photons.
