Abstract

A simple analysis is performed for the absorption properties of graphene; sandwiched between two media. For a proper choice of media and graphene doping/gating one can approach 50-100% absorption in the GHz-THz range for the one atom thick material. This absorption is controlled by a characteristic chemical potential which depends only on carrier life-time and the indexes of refraction of the dielectric embedding.

    • Some graphene facts that I've found after a few minutes of research: - One million times thinner than paper, one atom thick, it's considered a 2D material. http://www.chemistryviews.org/details/ezine/4976821/Is_Graph... - Strongest material, stronger than diamond.…
