What to know about Light controls nanoscale 'bubble' domains in a ferroelectric crystal

Researchers at Flinders University have discovered that light can control nanoscale 'bubble' domains in ferroelectric crystals, with the most significant changes occurring after the light is turned off. This finding, published in Advanced Functional Materials, suggests potential applications for more energy-efficient memory devices and computing technologies.
