Optical properties of two-dimensional honeycomb crystals graphene, silicene, germanene, and tinene from first principles
We compute the optical conductivity of 2D honeycomb crystals beyond the usual Dirac-cone approximation. The calculations are mainly based on the independent-quasiparticle approximation of the complex dielectric function for optical interband transitions. The full band structures are taken into accou...
