报告摘要：
The interfacial effects between graphene and other materials have been found to impoverish its genuine properties and, between them, uncontrollable rough morphology formation is one of the most harmful in terms of homogeneity and variability. We present the investigation of the morphology and performance of graphene on the substrates by using Scanning Tunneling Microscope, Atomic Force Microscope and simulation. Then, the properties of commercially available CAFM tips are modified by coating them with CVD-grown graphene. The resulting graphene-coated tip proved to be extremely stable and resistant in terms of mechanical durance and electrical characterization, such as high frictions and elevated current densities, respectively. The tips can also inhibit the sample interaction with the conductive tip coating, which is a source for false imaging.
