摘要:

For the first time we have observed a surface memory effect in liquid crystal cells where both surfaces consist of rubbed polymers. In this case the azimuthal orientation of the optical axis in the cell is unchanged, while the polar orientation of the optical axis in the cell changes. This change is brought about by imposing changes in the in-plane order of the molecules at the surface.
