Abstract

Characteristics of electroconvection patterns have been studied in a homeotropic nematic liquid crystal with unusual combination of material parameters (negative conductivity and positive dielectric permittivity anisotropies). The morphological phase diagram has been explored. Two distinct types of pattern dynamics have been detected: losing autocorrelation of the pattern during temporal evolution due to spatio-temporal chaos at onset and domain coarsening of a grid pattern.
