Strength of memory-induced anchoring of 5CB on bare untreated ITO
We realize uniform planar alignment of 5CB on isotropic untreated ITO substrate. The counterplate orientation is "imprinted'' on ITO and memorized by adsorption of an oriented nematic layer. We measure the azimuthal and the zenithal anchoring energies. We show that the memory induced anchoring strength is similar to the one usually found for substrates with high anisotropy. Studying rubbed ITO substrate, we show that in this case also the azimuthal anchoring is mainly due to memory effect.
