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