Single-layer graphene has very high charge carrier mobility but poor sheet resistance, to lower the resistance significantly and make it competitive with ITO multi-layer graphene is needed. But that has drawbacks in lack of transparency and control over the number of layers. If we could ensure low contact resistance with a sheet of single-layer graphene and minimize substrate interactions that reduce monility then it could prove to be far superior to traditional inorganic oxides.
