  • Graphene nanoribbons are potential systems for engineering topological phases of matter, but the pre-required gapped phases are difficult to find. Here, the authors show that chiral graphene nanoribbons undergo a transition from metallic to topological insulators, and then to trivial band insulators as they are narrowed down to nanometer widths.

  • Zig-Zag graphene nanoribbons have edge states that are predicted to be spin-polarized, however, measurement of these spin-polarized states has proved elusive. Here, Brede et al overcome this challenge by growing graphene nanoribbons on ferromagnetic GdAu2, allowing for the direct observation of the spin-polarized edge states.
