      abstract     = {We present electronic transport measurements on etched
                      graphene nanoribbons on silicon dioxide before and after a
                      short hydrofluoric acid (HF) treatment. We report on changes
                      in the transport properties, in particular, in terms of a
                      decreasing transport gap and a reduced doping level after HF
                      dipping. Interestingly, the effective energy gap is nearly
                      unaffected by the HF treatment. Additional measurements on a
                      graphene nanoribbon with lateral graphene gates support
                      strong indications that the HF significantly modifies the
                      edges of the investigated nanoribbons leading to a
                      significantly reduced disorder potential in these graphene
