Certain embodiments of the present invention include a versatile and scalable process, 'patterned regrowth,' that allows for the spatially controlled synthesis of lateral junctions between electrically conductive graphene and insulating h-BN, as well as between intrinsic and substitutionally doped graphene. The resulting films form mechanically continuous sheets across these heterojunctions. These embodiments represent an element of developing atomically thin integrated circuitry and enable the fabrication of electrically isolated active and passive elements embedded in continuous, one atom thick sheets, which may be manipulated and stacked to form complex devices at the ultimate thickness limit.
