Controlled defect formation and heteroatom doping in monolayer graphene using active oxygen species under ultraviolet irradiation

The introduction of micropores, reconstruction defects, and heteroatoms into monolayer graphene has been realized by utilizing photon energy in the ultraviolet (UV) region and reactive oxygen species. The defect density of monolayer graphene has been analyzed via the Raman spectral D/G intensity rat...
