Electrohydrodynamic Instabilities in Nematics with Homeotropic Boundaries

Part of the NATO ASI Series book series (NSSB, volume 116)


In experiments on thin films of nematic liquid crystals (NLC) two typical classical alignments of the director field are often used: vertical (homeotropic) or parallel (planar) to the boundaries. In this brief report we deal with experiments that are performed on thin homeotropic films of the nematic MBBA [N-(p-methoxybenzy-lidene)-p-butylaniline] having a negative dielectric anisotropy (Δε = εll - ε1 < 0).
