| 摘要: | Abstract-Scanning probe microscopes (SPM) are commonly used for characterization of the topographic and electrical properties of materials at the nanoscale. In such setup, the probes play a prominent role to obtain reliable imaging, but most tips lose their intrinsic properties after some measurements. Here, we modified the metal varnished atomic force microscope tips by transferring a sheet of graphene on them. The resulting graphene micro-electromechanical system (MEMS) � AFM tips are characterized by means of optical microscope, scanning electron microscope (SEM), energy dispersive Xray microscope (EDX) and atomic force microscope (AFM). Our graphene-coated tips achieved lifetimes 10 times larger than the uncoated counterparts, improving the quality and reducing the cost of research. |
