ABSTRACT
To thoroughly investigate the diversified electronic and optical properties in silicon (Si)-substituted graphene systems, the generalized tight-binding model directly links with the dynamic Kubo formula within the linear response. From the theoretical point of view, the Si-doped graphene systems have a lot of well-behaved distribution configurations. The high-symmetry ones, which correspond to the enlarged rectangular unit cells with achiral or chiral edge structures, are very suitable for the numerical calculations. The Si-decorated graphene exhibits the unusual low-energy electronic properties. Apparently, graphene exhibits a well-behaved Dirac cone (the dashed black curve) because of the purely hexagonal symmetry. In short, the experimental examinations on four kinds of Landau levels and the distinct magneto-optical selection rules could provide the full information about the diversified essential properties, establish the emergent binary or ternary graphene compounds, and confirm the developed theoretical framework.
