A theoretical design of inter-correlated in-plane and out-of-plane electric polarization in conventional perovskite ferroelectric thin films

ORAL

Abstract

Ferroelectric materials may have multiaxial electric polarization, in particular, in-plane and out-of-plane orientations for ferroelectric thin films, but the reversal of their electric polarization along different axes is normally independent. In this talk, I will present a theoretical design to make conventional perovskite ferroelectric thin films have inter-correlated in-plane and out-of-plane electric polarization, based on first-principles calculations. This work may lead to new device paradigms and applications based on conventional perovskite ferroelectric thin films.
