Electroconvection in a Homeotropic Bent-Rod Nematic Liquid Crystal Beyond the Dielectric Inversion Frequency

We characterize the structural transitions in an initially homeotropic bent-rod nematic liquid crystal excited by ac fields of frequency f well above the dielectric inversion point f i. From the measured principal dielectric constants and electrical conductivities of the compound, the Carr−Helfrich...
