Exploring the electronic confinement of Dirac fermions in Graphene nano-ribbons without degrading the outstanding properties of the mother material remains a delicate task for scientists.We know,for years,that an atomic cutting of a graphene flake along a crystallographic direction gives rise to a specific electronic band structure driven by the Dirichlet conditions,in close analogy with carbon nanotubes and their rolling vector.However,the presence of both short and long range potential disorder is detrimental.Only the mastering of the edge quality and orientation of sub-20nm wide graphene ribbons will allow a full benefit of their unusual 1D band structures,responsible for perfect conducting channels at low energy,spin-polarized edge states or a tuneable direct band-gap suitable for digital electronic applications.
