Thermoelectric Polarization Transport in Ferroelectric Ballistic Point Contacts
Ping Tang, Ryo Iguchi, Ken-ichi Uchida, Gerrit E. W. Bauer
Abstract
We formulate a scattering theory of polarization and heat transport through a ballistic ferroelectric point contact. We predict a polarization current under either an electric field or a temperature difference that depends strongly on the direction of the ferroelectric order and can be detected by its magnetic stray field and associated thermovoltage and Peltier effect.
