Characteristic Exponent of Normal and Oblique Rolls in Homeotropically Aligned Nematic Liquid Crystal

Translational flow in the low-frequency regime of electroconvection in parallelepiped sandwich cell of planar liquid crystal

“…1) Electroconvection can be observed by confining a negative dielectric anisotropic nematic LC between two parallel glass plates coated with transparent electrodes, treated to achieve a certain director  n (average molecules orientation), and then subjected to electric fields. Two common orientations used are homeotropic 2,3) ( n normal to the electrode surface) and planar [4][5][6][7] ( n parallel to the electrode surface) orientations.…”
