Hybrid 2D materials
While graphene has attracted a great deal of research due its remarkable electronic and mechanical properties, the difficulty of inducing an appreciable bandgap limits its use in nanoelectronic applications, particularly as a logic device. Graphene based heterostructures, combining graphene with other two dimensional materials, have been recently proposed in order to overcome this limitation. Particularly attractive are insulating hexagonal boron nitride (h-BN) or semiconducting transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2) and tungsten diselenide (WSe2). The hybridisation of graphene with other two dimensional materials opens up the possibility of engineering the band gap and realising synthetic two-dimensional alloys and topological insulators.
