This project employs direct writing with an atomic force microscope AFM to fabricate simple graphene-based electronic components like resistors and transistors at nanometer-length scales. The goal is to explore their electrical properties for graphene-based electronics. Conducting nanoribbons of graphene were fabricated using thermochemical nanolithography TCNL. TCNL uses a heated AFM cantilever to provide precise local heating to an insulating fluorographene FG substrate. The heat reduces the substrate into a material known as reduced fluorographene rFG, which exhibits electric properties similar to those of pristine graphene. Compared to other attempts to produce graphene-based devices, this technique is simple, does not involve solvents or other complicated fabrication steps, and allows for the exact placement of the devices on the wafer.
