Riassunto
During last two decades, after the discovery of graphene , two-dimensional materials attracted a huge interest in the condensed matter physicist community. The extraordinary transport properties of this materials, as well as the atomic scale thickness and good mechanical resistance, make it a credible candidate for the realisation of next-generation electronic components. Due to this interest, several others two-dimensional materials have been synthesised after graphene, like silicene , exfoliated molybdenum disulphide and boron nitride. Combining two-dimensional semiconductors with graphene, is a good way to tune its electronic properties. by mean of ab-initio Density Functional Theory and Time-Dependent Density Functional Theory calculations, we have studied the optical properties and the band structures of several in-plane heterostructures of graphene and boron nitride.
