Suspended graphene membrane NEMS. (a) Schematic of the suspended graphene membrane cavity and the nanoindentation measurement setup. As a result of the AFM tip indenting the graphene membrane, the charge gradient in this membrane is expressed by a color change. (b) The lithography-free process flow. (c) AFM and (d) optical microscope images of a typical sample containing a monolayer graphene channel. (e) FEM simulation of the suspended graphene membrane pressed by an AFM tip with a set point of 80 nm. AFM, atomic force microscope; NEMS, nanoelectromechanical systems.
