Abstract:
We have carried out a numerical study of the structural, thermodynamic, and anchoring properties of
organic liquid crystal (LC) films (OLCFs) deposited in vacuo on a solid surface. Calculations have been carried
out in the framework of the extended McMillan approach for anisotropic forces. The effects of surface
enhanced pair interactions in the bounding LC/solid and LC/vacuum layers and of film thickness on the
orientational and translational order parameters, as well as on Helmholtz free energy, entropy, and
anchoring energy of OLCFs have been investigated. A reasonable agreement between the theoretically
predicted and the experimentally obtained data on the anchoring energy of 4-n-octyl-40-cyanobiphenyl films has been obtained.
