Non-Ising and chiral ferroelectric domain walls revealed by nonlinear optical microscopy
Abstract
Understanding the structure of domain walls is an important step in developing nanoscale ferroelectric devices. Here, the authors use second harmonic imaging to verify predictions of Bloch and Néel, rather than simple Ising, domain wall structures in lead zirconium titanate and lithium tantalate.
