Properties and Applications of Ferroelectric Liquid Crystals
The ferroelectric modes of liquid crystals which allow for easy reorientation of the direction of polarization make liquid crystals an attractive element to use for applications such as optical storage, and optical switching. Three schemes for achieving ferroelectricity are discussed: chiral smectic alignment, achiral “banana-shaped” smectic alignment, and the nematic phase that comes from stro...
متن کاملOrientation dependence of electromechanical properties of relaxor based ferroelectric single crystals.
The orientation dependence of electromechanical properties of relaxor based ferroelectric single crystals Pb(Zn1/3Nb2/3)O3-(6-7)%PbTiO3 and Pb(Mg1/3Nb2/3)O3-33%PbTiO3 has been calculated by coordinate transformation. Different from previous studies, the optimum cutting orientations have been predicted in terms of their piezoelectric responses in the corresponding crystal planes. The calculation...
متن کاملEffective symmetry and physical properties of twinned perovskite ferroelectric single crystals
The effective symmetry and material properties of twinned ferroelectric crystals with perovskite structure were analyzed. The twins or twinbands studied here were formed during ferroelectric phase transitions, which resulted in one of the following symmetry changes: m3m → 3m, m3m → 4mm, and m3m → mm2. It was found that the volume ratios of the two domains in a twin structure were not always equ...
متن کاملSynthesis, Structural and Dielectric Properties of Ferroelectric Dichloridoglycine Zinc Dihydrate Single Crystals
The strong electro mechanical coupling exhibited by the ferroelectric materials is the remarkable feature of these materials. Therefore, they find applications in sensors, actuators for producing ultrasonics and micro positioning. The material dichloridoglycine zinc dihydrate is a centrosymmetric ferroelectric crystal. In the present study, this crystal has been grown from a mixture of glycine ...
متن کاملEPR of Cu*+ in Ferroelectric LiHs(SeOa)s Single Crystals
Lithium trihydrogen selenite, LiH3(Se03)2 (LHS) [1], due to its interesting features such as large dielectric polarization, presence of ferroelectricity up to its melting point, role of hydrogen bonds in the onset of ferroelectric behaviour, and so on, has been the subject of a number of investigations [2—5]. Jain and Venkateswarlu [6—7] have reported the EPR of Mn2+ and V02+ in LHS from 298 K ...
