ABSTRACT
Recent advances in the production, manipulation, and properties of graphene have established this material as a promising candidate for the next-generation building block for the electronics industry. While the development of integrated graphene electronics requires the utilization of traditional processes, such as lithography, it is vital to complement the existing methods with specic chemical strategies that can modulate selectively the optical and electronic properties of graphene-based devices. In this chapter, the application of various in-situ functionalization approaches on graphene deposited onto different types of substrates (polymeric, metallic, insulating, or semiconducting) is discussed. In addition, the effect of various environmental conditions (atmosphere, temperature) is analyzed in detail. Emphasis is given on the assessment of doping effects and structural changes of graphene lattice by optical spectroscopy means.
