Charged Domain Walls in Ferroelectrics

Abstract

Charged Domain Walls (CDWs) in ferroelectrics are compositionally homogeneous interfaces, some of which display metallic-like conductivity and can be created, displaced and erased inside a monolith of nominally insulating materials. Such CDWs are promising electronic elements for reconfigurable nanoelectronics. This chapter introduces types of CDWs, their theoretically predicted and experimentally observed properties, and methods of their artificial engineering.
