Heat transfer in extreme near-field regime – NEARHEAT

Submission summary

Radiative heat transfer in the near field (micron and sub-micron distances) can dramatically overcome the far-field blackbody limit, by means of photon tunneling. Even though in the extreme near field (sub-nanometric distances) electrons and phonons represent two important channels contributing to heat exchange, no complete theoretical framework has been proposed to tackle this multi-channel energy transfer so far. In this project we aim to develop such a general theory to describe the three contributions (photonic, electronic and phononic) to heat transfer by exploiting fluctuational electrodynamics for photons, and at the same time mesoscopic and ab-initio atomistic approaches for electrons and phonons. This will allow to improve significantly the efficiency of several energy-conversion techniques, such as thermoelectricity and near-field thermophotovoltaics, as well as of methods of contact-less cooling.
