"quasiparticle ferron carries waves of polarization and heat at the same timemight increase that change in thermal conductivity by up to 15%... application of an electrical field to the material produced a 2% difference between maximum and minimum conductivity... heat switches in everyday applications, like collection of solar power... heat-transferring property induced by electric field through piezoelectric strain: lattice contracts or stretches when voltage applied changing thermal conductivity"
