      abstract     = {We report the use of a surfactant molecule during the
                      epitaxy of graphene on SiC(0001) that leads to the growth in
                      an unconventional orientation, namely $R0^\circ$ rotation
                      with respect to the SiC lattice. It yields a very
                      high-quality single-layer graphene with a uniform
                      orientation with respect to the substrate, on the wafer
                      scale. We find an increased quality and homogeneity compared
                      to the approach based on the use of a pre-oriented template
                      to induce the unconventional orientation. Using spot profile
                      analysis low energy electron diffraction, angle-resolved
                      photoelectron spectroscopy, and the normal incidence x-ray
                      standing wave technique, we assess the crystalline quality
                      and coverage of the graphene layer. Combined with the
                      presence of a covalently-bound graphene layer in the
                      conventional orientation underneath, our surfactant-mediated
                      growth offers an ideal platform to prepare epitaxial twisted
                      bilayer graphene via intercalation.},
