Several methods are used to fabricate nanoscale transmission lines: - Chemical Vapor Deposition (CVD): This technique is commonly used to grow high-quality CNTs and graphene. - Electrospinning: A method for creating nanowires by utilizing an electrical charge to draw fibers from a liquid. - Lithography: Techniques like electron-beam lithography can create very fine patterns necessary for nanoscale transmission lines. - Self-Assembly: Molecules can be designed to self-assemble into desired structures, offering a bottom-up approach to fabrication.
