3d optical tomography of ferroelectric domains and domain walls
In ferroelectric materials, the spontaneous polarization can be reversibly switched by an applied electric field, which makes them attractive for applications in non-volatile memories and other electro-active devices. However, the complex domain structure and domain-wall motion in these materials re...

| Sumario: | In ferroelectric materials, the spontaneous polarization can be reversibly switched by an applied electric field, which makes them attractive for applications in non-volatile memories and other electro-active devices. However, the complex domain structure and domain-wall motion in these materials remains not fully understood. Here, we show a new method for three-dimensional optical tomography to study the domain structure and domain-wall motion in ferroelectrics. Our new method provides a new tool for studying the structure and the dynamics of domain and domain walls, that can be used to optimize the performance of ferroelectric devices. |
