摘要: Abstract Electroconvection (EC) in nematic liquid crystals, which appears before smectic C phase at cooling, was studied. Three detached regions with characteristic ECs were detected under temperature variation. The influence of the change magnitude and sign electroconductivity anisotropy, as well director location (both driven by variation), on EC mechanism relevant optical patterns are discussed. competition between two possible mechanisms: Carr–Helfrich ‘isotropic’ mechanism, is
