High optical absorption in graphene
Magazine article, 2012
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.
