Optical conductivity in an effective model for graphene: finite temperature corrections
Optical conductivity in an effective model for graphene: finite temperature corrections
In this article, we investigate the temperature and chemical potential dependence of the optical conductivity of graphene, within a field theoretical representation in the continuum approximation, arising from an underlying tight-binding atomistic model, that includes up to next-to-nearest neighbor coupling. Our calculations allow us to obtain the dependence of the …
