Abstract
Graphene is a two dimensional material consisted of honeycomb carbon lattices. Comparing to pure graphene, bilayer graphene is taking special interest due to the interlayer interactions. The interlayer coupling has the influences on the electronic and optical properties, which has crucial characteristics distinct from graphite. Ebernil et al. [1] reported that the single layer graphene has red-shifted surface plasmon modes from graphite at 4.7 eV and 14.6 eV. It illustrated that the dielectric function of graphene distinct from graphite. In this work, the permittivities of double layer graphene are numerically simulated using Density Functional Theory (DFT) method. Also, the transmittance of SiO2 substrate model, surface conductivity approach of graphene model, and DFT model are compared.
