Electric control of the heat flux through electrophononic effects
arXiv:1805.08213 · doi:10.1103/PhysRevB.97.184306
Abstract
We demonstrate a fully electric control of the heat flux, which can be continuously modulated by an externally applied electric field in PbTiO, 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.
