Claims3
A graphene and liquid crystal device consisting of:
- a substrate;
- a layer of graphene on the substrate;
- a layer of liquid crystal on the layer of graphene;
- and
- π-π electron stacking;
- wherein the molecules of the layer of liquid crystal and the layer of graphene are aligned;
- wherein alignment of the liquid crystals is controlled by a voltage applied wherein the layer of graphene serves as an electrode;
- further comprising a uniform planar aligned state of the molecules of the layer of liquid crystal;
- and
- wherein the layer of graphene is an alignment layer and
- an electrode for a liquid crystal device;
- wherein the graphene and liquid crystal device is heated;
- wherein the graphene and liquid crystal device is cooled;
- wherein the layer of liquid crystals comprised liquid crystals in the isotropic phase before the step of heating the graphene and liquid crystal device,
- wherein the layer of liquid crystals comprised liquid crystals in the nematic phase after the step of cooling the graphene and liquid crystal device;
- and
- wherein the affinity of phenyl rings with one another comprises π-π stacking and drives alignment of the layer of liquid crystal molecules and the layer of graphene.
