Subsecond optically controlled domain switching in freestanding ferroelectric BaTiO₃ membrane.

ABSTRACT: The quest to develop energy-efficient and fast optoelectronic control of memory devices is essential. In this respect, ferroelectric materials are gaining tremendous importance in information and communication technology. Here, we demonstrate light-controlled polarisation switching on a subsecond timescale ( <500 ms) in a freestanding BaTiO3 membrane, which is nearly 1200 times faster than the previously reported response using a BaTiO3 thin film. We reveal the potential of optically controlled computing by demonstrating the associated resistance change in the membrane as a result of the polarisation reversal induced by illumination. By combining theoretical and experimental studies, we demonstrate that the imprint effect coupled with the reduced energy barrier of domain wall motion influe
