Forming long graphene nanoribbons less than 10 nanometers wide is possible—if water is added into the mix. Researchers discovered that a bit of water adsorbed from the atmosphere was found to act as a mask in a process that begins with the creation of patterns via lithography and ends with very long, very thin graphene nanoribbons. The ribbons form wherever water gathers at the wedge between the raised pattern and the graphene surface. The team describes the method in a study published in the journal ACS Nano.
