Abstract: We demonstrate that the Raman intensities of G and 2D bands of a suspended graphene can be enhanced using a gold tip with an apex size of 2.3 μm. The enhancement decays with the tip-graphene distance exponentially and remains detectable at a distance of 1.5 μm. Raman mappings show that the enhanced area is comparable to the apex size. Application of a bias voltage to the tip can attract the graphene so that Raman signals are intensified. The exponential enhancement-distance relationship enables the measurement of the graphene deformation, and the Young's modulus of graphene is estimated to be 1.48 TPa.
