▎ 摘 要
NOVELTY - The method involves coating a base by a first polymeric layer. A probe (11) is attached over the first polymeric layer. The probe is coated by a second polymeric layer. A polymeric substrate is deposited by a graphene layer over the second polymeric layer. The polymeric layers are dissolved by a solvent agent, such that graphene layer is attached to a surface of the probe. USE - Method for coating graphene on probe e.g. platinum/iridium varnished probe (Claimed) for atomic force microscope. ADVANTAGE - The dissolving step is carried out over a period of approximately 30 minutes to assure the smoothness of the etching process, so that falls and breakages of the probe can be prevented. The coating process is developed over the conductive surface of an atomic force microscope tip using a graphene single layer film. The tip of probe is totally coated with graphene, so that higher resistant is provided to both high currents and frictions than commercially available metal-varnished CAFM tips. Thus, lifetime can be extended and reliable imaging is achieved due to a lower tip-sample interaction. The camera serves as vapor enclosure to increase etching yield and constant etching on the entire sample. The camera remains open on the top to avoid that drops of condensed acetone precipitate on the sample. The poly-methyl methacrylate (PMMA) layers are dissolved gradually and simultaneously without losing a horizontal position, so that slippage into the boiling acetone can be avoided. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a probe for an atomic force microscope. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the platinum/iridium varnished probe. Probe (11) Cantilever (12) Silicon substrate (81) Conductive layer (82)
