Phys. Rev. E 64, 042701 (2001) [4 pages]Surface polarization and effective anchoring energy in liquid crystalsReceived 8 May 2001; published 25 September 2001 The influence of the surface polarization (SP) on the effective anchoring energy for both homeotropic and planar alignments of polar liquid crystals at a solid substrate is discussed from the energy point of view. It is shown that in a certain range of surface charge density the destabilizing SP mechanism may lead to destruction of the homeotropic or planar alignment of liquid crystalline molecules, such as 4-n-pentyl-4′-cyanobiphenyl. © 2001 The American Physical Society URL:
