| Research Abstract |
Developing lead-free dielectric and piezoelectric materials is urgent however, the developing runs into difficulties. The proposal will aim to find a road map to lead-free materials by studying the lead-based perovskite relaxor ferroelectrics, which is mainly used in the industry, with the speckle-time-correlation spectroscopy which is under development in SPring-8 as a technique for nano-condensed matter physics.
