I wonder graphene is conductive enough to replace silver for example in a real practical sense to replace the copper interconnect for example in a chip. It seems that it has reported good conductivity and yet when it comes to practical conductivity compared with ITO it doesn't seem to score better when device is made. Please comment.
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.
