Charge screening in ferroelectric Pb(Zr,Ti)O3 nanorods was used to control their domain pattern. The c-domain fraction markedly increased with as the rod width decreased, while the a-domain formation prevailed by metallization of their sidewall. All the observed results could be explained by the depolarizing field, arising from the imperfect charge screening. This approach could be expanded to other low-dimensional nanoscale ferroelectric systems. Credit: Tomoaki Yamada
Scientists have taken control of the configuration of domains in nanorod- and thin-film ferroelectric systems. Many next-generation electronic and electro-mechanical device technologies hinge on the development of ferroelectric materials...
