NEAR FIELD HEAT TRANSFER

We reported for the first time the existence of Fano resonances in the spectral near-field radiative heat transfer by combining metallic and polaritonic materials. By tuning the plasma frequency of the metal to the longitudinal phonon frequency of the polaritonic material. Extensions of this work, we introduced the concept of thermal band-gaps. Similarly, we are interested is the use of mesoporous materials, in particular metals, to control the radiative heat transfer.
We are working on the use of 2D material superlattices to control the heat transfer at the nanoscale.
