Researchers are studying the atomic-scale structure of lead-free materials, such as Bi, to understand their dynamic electromechanical response. The studies involve various materials and techniques, including field-driven dipolar ordering and solid-solution-induced entropy increase, to observe and analyze their electrical properties. The goal appears to be deciphering the origins of large dynamic responses in these materials, with potential applications in areas like energy capacitive relaxors and piezoceramics.
