ABSTRACT
Graphene is a material that is one atom thick and has a high conductivity, high mobility of charge carriers, a high thermal conductivity, and a large number of other attractive properties (Geim 2009, Novoselov et al. 2012). Moreover, from this material, many graphene-based dielectrics, such as oxidized, hydrogenated, and ‰uorinated graphene, can be obtained (Bera et al. 2010, Soldano et al. 2010, Bimberg and Pohl 2011). Fabrication of new graphene-based materials that involve quantum structures and are obtained by means of graphene local functionalization is widening considerably the potential applications targeted by graphene (Craciun et al. 2013). Quantum dot (QD) systems offer materials that have the potential for many applications in physical, chemical, and biological areas, such as optoelectronic, photovoltaic, and memory devices, sensors, bioimaging systems, and medicine (e.g., Shao et al. 2012, Shen et al. 2012, Li et al. 2013). Currently, signi cant progress has been made in the creation of graphene quantum dots (G-QDs) and the investigation of their properties (Ponomarenko et al. 2008, Güttinger et al. 2012).
