Flexoelectricity in Liquid Crystals:Theory, Experiments and by Ágnes Buka,Nándor Éber

By Ágnes Buka,Nándor Éber

The e-book intends to provide a cutting-edge review of flexoelectricity, a linear actual coupling among mechanical (orientational) deformations and electrical polarization, that is particular to platforms with orientational order, comparable to liquid crystals.

Chapters written through specialists within the box make clear theoretical in addition to experimental elements of analysis performed because the discovery of flexoelectricity. along with a standard macroscopic (continuum) description the microscopic idea of flexoelectricity can also be addressed. Electro-optic results because of or converted by way of flexoelectricity in addition to quite a few (direct and oblique) size tools are mentioned. exact emphasis is given to the position of flexoelectricity in pattern-forming instabilities.

While the main target of the publication lies in flexoelectricity in nematic liquid crystals, peculiarities of different mesophases (bent-core structures, cholesterics, and smectics) also are reviewed. Flexoelectricity has relevance to organic (living) structures and will additionally supply percentages for technical purposes. the fundamentals of those interdisciplinary fields also are summarized.
