AI Article Synopsis
- Ferroelectric domain walls are important for nanoelectronic devices due to their sensitivity to external stimuli, particularly optical signals.
- Researchers demonstrated that in-plane polarized subdomains in ferroelectric BaTiO can be controlled optically, allowing for reversible movement of domain walls.
- The study also suggests that flexoelectricity, rather than long-range ferroelectric polarization, plays a crucial role in optical control, making ferroelastic materials viable for future nanoelectronics.
Article Abstract
The sensitivity of ferroelectric domain walls to external stimuli makes them functional entities in nanoelectronic devices. Specifically, optically driven domain reconfiguration with in-plane polarization is advantageous and thus is highly sought. Here, we show the existence of in-plane polarized subdomains imitating a single domain state and reversible optical control of its domain wall movement in a single-crystal of ferroelectric BaTiO. Similar optical control in the domain configuration of nonpolar ferroelastic material indicates that long-range ferroelectric polarization is not essential for the optical control of domain wall movement. Instead, flexoelectricity is found to be an essential ingredient for the optical control of the domain configuration, and hence, ferroelastic materials would be another possible candidate for nanoelectronic device applications.
