Two-tip STM conductance characteristics of individual planar graphene nanoribbon

Project description

Probing the electronic conductance properties of graphene nanoribbons

Graphene nanoribbons, narrow 1D stripes of graphene with widths in the nanometer range, are promising building blocks for nanoelectronics. Obtaining detailed electronic information such as their intrinsic charge transport is essential when evaluating candidates for high-performance electronic devices. The EU-funded GNR CONDUCTANCE project plans to measure the conductance of individual graphene nanoribbons in the lateral planar configuration using multi-tip scanning tunneling microscopy (STM). In particular, it will investigate graphene nanoribbons around 1–2 nm wide and 20–100 nm long, synthesised on top of a gold substrate. For accurate measurements, special focus will be placed on ensuring the STM tips form stable contacts with the graphene nanoribbons. To electrically decouple graphene nanoribbons from the gold substrate, the project will use intermediate ultrathin insulating NaCl layers.
