Formation of Monolayer Films of Graphite Nano-crystals and Graphite Nano-ribbons

Self-Standing Graphene Sheets Prepared with Chemical Vapor Deposition and Chemical Etching

“…The origin of the structure is not clear now. Since graphene nano-ribbons and hetero-epitaxial double sheets grew on solid surfaces by CVD techniques [8,23,24], self-standing nano-ribbons of graphene, and self-standing hetero-epitaxial films are presumably prepared by removing the substrate with the chemical etching as demonstrated in this paper.…”
