the decade has witnessed the invention of, and dramatic development in knowing the physics of graphene and comparable two-dimensional fabrics. the improvement of equipment for production and aligning top of the range two-dimensional crystals has facilitated the construction of a brand new new release of fabrics: the heterostructures of graphene with hexagonal crystals, within which the graphene electrons gather new, qualitatively various houses. This thesis offers a finished theoretical framework during which to appreciate those heterostructures, in response to the tight binding version, perturbation idea, staff conception and the concept that of the moire superlattice (all of that are elucidated). It explains how graphene heterostructures supply new possibilities for tailoring band constitution, similar to developing extra Dirac issues or starting band gaps and the way they show up themselves in shipping measurements, optical absorption spectra and the fractal Hofstadter spectra. additionally thought of are the heterostructures of bilayer graphene and resonant tunneling in aligned graphene/insulator/graphene devices.
