Injection and controlled motion of conducting domain walls in improper ferroelectric Cu-Cl boracite.

ABSTRACT: Ferroelectric domain walls constitute a completely new class of sheet-like functional material. Moreover, since domain walls are generally writable, erasable and mobile, they could be useful in functionally agile devices: for example, creating and moving conducting walls could make or break electrical connections in new forms of reconfigurable nanocircuitry. However, significant challenges exist: site-specific injection and annihilation of planar walls, which show robust conductivity, has not been easy to achieve. Here, we report the observation, mechanical writing and controlled movement of charged conducting domain walls in the improper-ferroelectric Cu₃B₇O₁₃Cl. Walls are straight, tens of microns long and exist as a consequence of elastic compatibility c
