Radiative heat transfer between nanoparticles: shape dependence and three-body effect

TL;DR

This paper investigates how the shape of nanoparticles influences radiative heat transfer in a three-body system, revealing that shape mismatches can significantly enhance or suppress heat flux.

Contribution

It demonstrates the shape dependence of radiative heat transfer and shows how the third particle's shape can tune the heat flux between two nanoparticles.

Findings

Heat flux is highly sensitive to particle shape mismatches.

Shape tuning can enhance or suppress heat transfer.

Three-body interactions significantly affect radiative heat transfer.

Abstract

We study the effect of particles shape on the radiative heat transfer in a three-body system. It is found that the radiative heat flux between two nanoparticles in a three body system can be tuned by the shape of the third particle. In particular, we show that the heat flux is very sensitive to the particle shapes and slight mismatches of shapes results in either enhanced or suppressed heat flux.
