Nd:YAG Laser Damage of Graphene-Nickel Interfaces

In this work we investigate the damage induced on a graphene-nickel interface after the exposure to Nd:YAG infrared laser radiation. The damage threshold has been experimentally determined. We observe that once the fluence exceeds the threshold value, both the morphology and the physical-chemical properties of the samples change. This has been verified by scanning probe microscopes measurements and near edge x-ray absorption fine structure spectroscopy analysis.
