摘要

Relaxors exhibit unique dielectric response properties such as diffuse phase transitions and strong dispersion of the dielectric constant. The origin of these properties is still not fully understood. Here, we review our work on using first-principles-based methods to elucidate the connections between composition, local structure and dynamics in Pb-based relaxors.
