Electric control of the heat flux through electrophononic effects

Abstract

We demonstrate a fully electric control of the heat flux, which can be continuously modulated by an externally applied electric field in PbTiO${}_3$, a prototypical ferroelectric perovskite, revealing the mechanisms by which experimentally accessible fields can be used to tune the thermal conductivity by as much as 50% at room temperature.
