(Nanowerk News) Ferroelectric materials are unusual because they have an electrically positive side and an electrically negative side, and these sides can be switched with an electric field. Relaxor ferroelectrics are special ferroelectric materials with greatly enhanced electrical and mechanical properties. These properties originate from the materials’ domain structure. These are microscopic areas where the direction of polarization is aligned. Knowing how quickly these material’s properties can change is critical to understanding and using them.
