| Research Abstract |
Nanosized ferroelectrics of high quality, such as ultrathin films, nanoislands, nanorods and nanotubes, were fabricated and their physical properties, especially polarization switching behaviors, were investigated. Quantitative measurements of spontaneous polarizations in ultrathin PbTiO_3 films and nanoislands, which had been difficult to be measured before this study, were achieved. It was found that PbTiO_3 nanorods and nanotubes exhibited larger strains induced by electrical fields than those of thin films.
