This letter presents a graphene-based liquid crystal device with electrodes made of graphene, demonstrating excellent performance with a high contrast ratio. Graphene, a single-atom-thick, optically transparent, chemically inert, and excellent conductor, is a promising candidate for transparent conductive films in photonic devices. Compared to conventional metal oxides like ITO, graphene offers lower resistivity, higher transparency, and better chemical stability. Graphene is the first two-dimensional material, with unique properties such as high crystallographic quality and ballistic electron transport. It is an attractive material for optoelectronic devices due to its high optical transmittance, low resistivity, high chemical stability, and mechanical strength. Transparent conductors are essential in many optical devices, but traditional materials like ITO have limitations in terms of cost, complexity, and chemical stability. Carbon nanotube films have been used as alternatives, but graphene offers a new, promising alternative. Graphene-based transparent conductors have been used in various photonic devices, including electric field-activated optical modulators, organic solar cells, and liquid crystal displays. In this study, graphene is used as a transparent conductive coating for photonic devices, showing high transparency and low resistivity, making it ideal for electrodes in liquid crystal devices. Graphene's mechanical strength, chemical stability, and inertness make it suitable for improving the durability and simplifying the technology of optoelectronic devices. Graphene flakes were prepared by micromechanical cleavage and used as electrodes in liquid crystal devices. The devices were fabricated using graphene-on-glass films as one of the transparent electrodes. The other substrate was a glass slide coated with conventional ITO. Both substrates were coated with a polyvinyl alcohol alignment layer. The device was filled with nematic liquid crystal material E7. Applying a voltage across the liquid crystal layer distorts the crystal alignment, changing the effective birefringence of the device and altering the transmitted light intensity. The study also assesses the quality of the liquid crystal devices, focusing on the transparency of graphene, its resistivity, and chemical stability. Graphene's high transmittance is due to its low electronic density of states. The sheet resistance of undoped graphene is about 6kΩ, but it can be reduced to 50Ω by chemical doping. The study also discusses the chemical stability of graphene, which should minimize ion diffusion. The capacitance of one of the liquid crystal devices was measured, showing no hysteresis at the opposite polarity, indicating that graphene does not inject ions into the liquid crystal. The study also discusses the feasibility of mass production of graphene-based transparent conductors. Although micromechanical cleavage is not suitable for commercial production, chemical exfoliation of graphite oxide and reduction to graphene could lead to viable methods for producing thin graphene-based films. The study proposes an alternative approach using direct chemical exfoliation of graphite to obtain transparent conductiveThis letter presents a graphene-based liquid crystal device with electrodes made of graphene, demonstrating excellent performance with a high contrast ratio.
