FVOG stands for "First Vertical of Graphene" and it refers to the first layer of graphene atoms that are stacked vertically in a graphene stack. Some synonyms for FVOG are "monolayer graphene," "single-layer graphene," and "one-atom-thick graphene." These terms all describe the same thing - a layer of graphene that is only one atom thick and has unique physical and electrical properties. FVOG is of great interest to scientists and engineers because it has potential applications in fields such as electronics, energy storage, and biomedicine. By studying and manipulating FVOG, researchers hope to unlock the full potential of this remarkable material.
