- Аннотация: It was established that the surface energy of the carbon films could be varied over a wide range by adjusting the deposition conditions and the atomic surface structure. The surface energy of the carbon films can have an influence on the orientation of the epitropic liquid crystal molecules. This paper descrives the correlation between the structure and properties of Diamond Like Carbon (DLC) films and the orientation of epitropic liquid crystals. The optical dichroism technique eas used to determine the type of orientation on the epitropic liquid crystals. The orientation order parameter "s" was calculated for DLC films with different degrees of lyophilicity. The crystal surface tension was calculated from the angles of contact of epitropic liquid crystals on SiO2 substrates covered by DLC films. The experimental results have shown that varying the lyophilic nature of DLC films one can obtain the optimized conditions for orientation of thin liquid crystal layers. The results obtained show that the DLC films investigated are characterized not only by the ability to control the liquid crystal orientation but also have the ability to create liquid crystal layers with a controlled thickness. In conclusion the possibilities of applying DLC as an orientation layer in microelectronic devices will be discussed.
