  Doping is one of the most prominent techniques to alter properties of a given
material. Herein, the influence of the electron- and hole-doping on the
selected superconducting properties of graphene are considered. In details, the
Migdal-Eliashberg formalism is employed to analyze the specific heat and the
critical magnetic field in the representative case of graphene doped with
nitrogen or boron, respectively. It is found that the electron doping is much
more favorable in terms of enhancing the aforementioned properties than its
hole counterpart. These findings are appropriately summarized by the means of
the dimensionless thermodynamic ratios, familiar in the
Bardeen-Cooper-Schrieffer theory. To this end, the perspectives for future
research on superconductivity in graphene are drawn.
