| Research Abstract |
Strategy for lead-free ferroelectric and piezoelectric materials with perovskite-type structure was obtained based on the new idea based on the chemical bonds and crystal structures. As a result, many candidate materials were found out as well as new interpretation on the mechanism for the evolution of known ferroelectric materials. Thin films of novel compounds, which are not available by the conventional solid state technique, were also successfully obtained by the pulsed laser deposition technique.
