Ferroelectricity is a symptom of inevitable electrical polarization changes in materials with‐ out external electric field interference. Ferroelectricity is a phenomenon exhibited by crystals with a spontaneous polarization and hysteresis effects associated with dielectric changes

1. Our introductory chapter focuses on ferroelectrics and its aplications.

density microstructured BaTiO3 electroceramic material.

2. Rongli Gao et al. study transverse photovoltaic effects as a function of sample di‐ rections in-plane as well as the angle between the linearly polarized light and the plane of the sample along X and Y directions. A sample was made, tetragonal Bi‐ FeO3 film with a thickness of 30 nm, which was grown epitaxially on (001)-ori‐

3. Xin Chen et al. review the nonlinear optical effects that are bundled with ferro‐ electric domain walls or whose properties can be significantly enhanced by the

4. Alexander Skaliukh presents prevalent mathematical models of irreversible proc‐ esses in polycrystalline ferroelectric materials when they are subjected to intense

5. Amarilis Declet-Vega et al. report their studies on mechanical and dielectric prop‐

6. Phan Trong Tue and Yuzuru Takamura contribute their work on lead zirconium titanate films and devices made by a low-temperature solution-based process. 7. Bharat G. Baraskar et al. discuss the strategy to develop superior quality, high-

8. Liuxia Ruan et al. describe the preparation and device applications of ferroelectric

We have been researching ferroelectric materials since 2001, but there is still a blue ocean of ferroelectric applications yet to be elaborated. It is and hopefully always will be a bright future.
