Gold nanocages can be used to induce ferroelectric-to-paraelectric phase transitions by plasmonic heating. In their Communication on
page 13828 ff., Y. Xia and co-workers demonstrate the capability of this strategy by fabricating a patterned array of microscale ferroelectric domains in a poly(vinylidene fluoride) thin film in just a few seconds. Such patterned films are expected to find applications in sensing and actuating, and as flexible ferroelectronics.
