We report experimental and theoretical results on the flexoelectric instability and crossover between flexoelectric domains and electro-convection in a hybrid aligned nematic MBBA under d.c. voltage. At threshold a spatially periodic flexoelectric deformation in the form of longitudinal domains (along the planar director) was observed. With increasing voltage the director deviation out of the i...
متن کاملOptical Characterization of Electroconvection in Nematics
We describe non-standard techniques for optical studies of electrocon-vection structures in nematics. The time-resolved textures in the high frequency oscillatory regime are analyzed and compared with results of optical simulations. Conclusions on the relation between director pattern and optical texture are drawn. Using an additional phase plate in the optical setup , we monitor director twist...

متن کاملFlexoelectric E ect in Biaxial Nematics
The exoelectric e ect provides a linear coupling between electric polarization and orientational deformation in liquid crystals. It in uences many electrooptical phenomena and it is used in some bistable nematic devices. A statistical theory of dipole exoelectric polarization in biaxial nematic liquid crystals is used to calculate temperature dependence of order parameters, elastic constants, a...
متن کاملComment on "Optical determination of flexoelectric coefficients and surface polarization in a hybrid aligned nematic cell".
We argue that the experimental determination of the flexoelectric coefficients and the surface polarization of the p-pentyl-cyanobiphenil liquid crystal, recently reported by Mazzulla et al. [Phys. Rev. E 64, 021708 (2001)] is questionable. This conclusion follows from the hypothesis performed by the authors to extract the flexoelectric coefficients and the surface polarization from the reflect...
