We report the etching of and electronic transport in nanoribbons of graphene sandwiched between atomically flat hexagonal boron nitride (h-BN). The etching of ribbons of varying width was achieved with a focused beam of 30 keV He<sup>+</sup> ions. Using in-situ electrical measurements, we established a critical dose of 7000 ions nm<sup>−2<...
