▎ 摘　　要

NOVELTY - The device has a graphene layer formed on a substrate, and a liquid crystal layer formed on the graphene layer. The graphene layer is arranged with an alignment layer and an electrode for a liquid crystal module. Another graphene layer is formed on the liquid crystal layer, where affinity of phenyl rings with one another is maintained at specific level to drive alignment of liquid crystal molecules and the graphene layer. The electrode is adapted for switching orientation of the liquid crystal layer, where alignment of the liquid crystals is controlled by voltage applied to the graphene layer. USE - Graphene and liquid crystal device for an electro-optic liquid crystal device. Uses include but are not limited to a polarization grating, transmissive display device, reflective tunable filter and refractive waveguide such as steerable electro-evanescent optical refraction waveguide. ADVANTAGE - The device is capable of controlling conductive and aligning functions with a single layer of material so as to minimize scattering loss and optimize throughput of light over wide range of spectral bands, while reducing number of layers in the device and optical path length of the device, thus simplifying device fabrication process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for making a graphene and liquid crystal device. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a liquid crystal device with a graphene alignment layer.
