Yachin Ivry, Daping Chu, James F. Scott and Colm Durkan Domains Beyond the Grain Boundary Advanced Functional Materials 21
By imaging a common piezoelectric material with nanometer resolution, we demonstrate that domains are organized into areas with a correlated alignment of the ferroelastic and ferroelectric domains, spanning multiple grain boundaries. This paves the way towards explaining long-range collective phenomena observed in such materials. We present five typical arrangements of such structures: azimuthal, radial, gradient, and short- and long- range linear domain organizations.
