Title: Radiation stability of graphene under extreme conditions

In this letter, we report radiation stability of graphene under extreme condition of high energy density generated by 150 MeV Au ion irradiation. The experiment reveals that graphene is radiation resistant for irradiation at 10{sup 14 }ions/cm{sup 2} of 150 MeV Au ions. It is significant to note that annealing effects are observed at lower fluences whereas defect production occurs at higher fluences but significant crystallinity is retained. Our results demonstrate applicability of graphene based devices in radiation environment and space applications.
