Observing Correlated Production of Defects and Antidefects in Liquid Crystals
We present observations of strength one defects and antidefects formed in isotropic-nematic phase transition in a thin layer of nematic liquid crystals, using a cross-polarizer setup. We measure the widths of the distributions of net winding number in small regions, and determine the exponent characterizing the correlation between defects and antidefects to be 0.26±0.11, in very good agreement ...
متن کاملObserving Correlated Production of Defects-Antidefects in Liquid Crystals
We present observation of strength one defects and antidefects formed in isotropic-nematic phase transition in nematic liquid crystals using a crosspolarizer setup. We measure the width σ of the distribution of net winding number in two dimensional regions, each containing an average of 10 defects and antidefects. We find σ = 1.19± 0.04, in good agreement with the value 1.02 or 1.26 (for triang...
متن کاملEffects of Vacancy Cluster Defects on Electrical and Thermodynamic Properties of Silicon Crystals
A first-principle plane-wave pseudopotential method based on the density function theory (DFT) was employed to investigate the effects of vacancy cluster (VC) defects on the band structure and thermoelectric properties of silicon (Si) crystals. Simulation results showed that various VC defects changed the energy band and localized electron density distribution of Si crystals and caused the band...
متن کاملNematic Liquid Crystals: Defects
There are two types of defects in the uniaxial nematic F phase: line defects (disclinations) and point defects (hedgehogs and boojums). These are reviewed at three levels: (i) experimental observations; (ii) topological classification; and (iii) curvature elasticity. The reader is referred to the textbooks on liquid crystals (Chandrasekhar 1992, de Gennes and Prost 1993), defects (Kltman 1983),...
متن کامل-module defects in crystals
An analysis is presented of the new types of defects that can appear in crystalline structures where the positions of the atoms and the unit cell belong to the same {\bb Z}-module, i.e. are irrational projections of an N > 3-dimensional (N-D) lattice Λ as in the case of quasicrystals. Beyond coherent irrationally oriented twins already discussed in a previous paper [Quiquandon et al. (2016). Ac...
