Schematic illustration of the thickness dependent orientation of poly(ethylene oxide)-based azobenzene-containing liquid crystal (LC) polymer films (PEO-PAz) (upper). Below a critical thickness (<70 nm), this polymer exhibits a planar orientation (case e in Figure 4). Schemes of PEO orientation following surface relief grating (SRG) formation after irradiation with interference argon ion laser beams (lower). The in-plane orientation of PEO cylinders depends on the polarization mode of the laser beam. Adapted with permission.118 Copyright 2006, John Wiley & Sons.
