Re: Contradiction? @ chemist
It would work that way if you consider the graphene not as a sheet of carbon, but two layers of hydrogen stabilised by a lattice of carbon + electron soup ( extremely simplified, of course).
To migrate to the silicon any copper atom would have to react with the H of the graphene first.. and there it stops, really. Given the purity of the environment, only direct synthesis would be possible, and while the gods of Quantum could pull a fast one and provide the energy, the local temperature would ensure any CuH formed would revert near-immedeately. ( reverse reaction "happens readily" at 20 K, let alone 20 C...)
Then there is the issue of inserting into/breaking the benzene-ring lattice itself. And the Si-facing layer of H in the sheet ( with even more ...impressive... energies in play..). Let's just say the odds are stacked against it.
