Abstract: (1448 Views)
In this paper, the optical properties of bi-layer graphene in Bernal phase with different impurities are calculated for three cases (gr + Se / gr + Ga), (gr + Se / gr + P) and (gr + Se / gr + S). For the case of (gr + Se / gr + Ga) in two ranges, (12.015-12.425eV) with a maximum depth of -0.318 and (16.215-16.965eV) with a maximum depth of -0.676, the value of 
is negative, whereas in these two ranges 
is positive, therefore, this behavior is the responsible for the formation of plasmons. For the region of (E <10eV), the absorption spectrums of all three structures have significant differences that are applied in various optical fields.
