摘要

The surface-assisted photoalignment effect of dye-doped liquid-crystal films was examined that had a homogeneous alignment. A polarizing optical microscope, a scanning electronic microscope and an atomic force microscope were used for the study. It was found that the morphology of the laser-induced surface-adsorbed dyes at the command surface strongly affected the orientation of liquid crystals (LC). The results show that in the high-intensity regime, rough and inhomogeneous ribbonlike adsorbents form on the top of the performed microgrooves, thus reorienting LC's.
