Chemical nanopatterns via nanoimprint lithography for simultaneous control over azimuthal and polar alignment of liquid crystals
Chemical nanopattems down to 50 am in feature size have been fabricated via nanoimprint lithography and used to simultaneously control azimuthal and polar orientation of liquid crystals (LCs), The polar orientation depends on the ratio of the homeotropic/planar surface potential areas, while the LC azimuthally orients along the direction of the silane patterns (see Figure).
