Influence of an electric field on the optical properties of few-layer graphene with<i>AB</i>stacking

The effect of perpendicular electric field $(\mathbf{F})$ on optical properties of the AB-stacked few-layer graphene, made up of two, three, or four graphite sheets, is explored through the gradient approximation. In contrast to the featureless optical spectra of graphene, the low-energy absorption ... View More
