Laser-assisted chemical reactions have been used to write reversible ultra-high-density doping patterns in graphene for optoelectronic applications. The approach used two laser beams with specific photon energies and geometric configurations to enable local doping with a high dopant coverage ratio on graphene, while preserving the electronic properties of the surface.
