Geometric frustration is a broad phenomenon that results from an intrinsic incompatibility
between some fundamental interactions and the underlying lattice geometry,,,,,,. Geometric …

A piezoelectric material is one that generates a voltage in response to a mechanical strain
(and vice versa). The most useful piezoelectric materials display a transition region in their …

Complex insulating perovskite alloys are of considerable technological interest because of
their large dielectric and piezoelectric responses. Examples of such alloys include (Ba1-x Sr …

Bulk ferroelectrics undergo structural phase transformations at low temperatures, giving
multi-stable (that is, multiple-minimum) degenerate states with spontaneous polarization …

A detailed ab initio model of ferroelectric ordering in thin films shows that phase transitions
and ferroelectric bistability occur down to diameters of 3.2 nm in nanodisks and nanorods …

The characteristic functionality of ferroelectric materials is due to the symmetry of their
crystalline structure. As such, ferroelectrics lend themselves to design approaches that …

The wealth of complex polar topologies,,,,,,,,–recently found in nanoscale ferroelectrics
results from a delicate balance between the intrinsic tendency of the materials to develop a …

Phase transition describes a mutational behavior of matter states at a critical transition
temperature or external field. Despite the phase-transition orders are well sorted by classic …

The existence of domain walls, which separate regions of different polarization, can
influence the dielectric, piezoelectric, pyroelectric and electronic properties, of ferroelectric …

SIR-Cohen 1, using total energy calculations, ascribes the origin of ferroelectricity in BaTi03
and PbTi03 to transition metal-oxygen pd hybridization effects. Here, we emphasize that this …
