摘要：

A planar liquid crystal (LC) cell is designed by placing together a monolayer graphene coated glass slide and a planar-aligning polyimide layer on an indium tin oxide (ITO) coated glass slide. It is shown that the monolayer graphene film on one side of the cell can serve as the planar-alignment agent. At the same time, the monolayer graphene film also functions as the transparent electrode. The successful optical and electro-optical operations of this hybrid LC cell with monolayer graphene on one side and with ITO and associated planar-aligning polyimide on the other side are demonstrated. The measured optical transmission of the graphene electrode is found to be much better than that of the combined ITO-PI layers. The electro-optical effect and the dynamic electro-optic response of the LC in this graphenepolyimide-based hybrid cell reveal the typical director reorientation of the LC on the application of an electric field.
