      abstract     = {We report the formation of a bilayer Bi(111) ultrathin
                      film, which is theoretically predicted to be in a
                      two-dimensional quantum spin Hall state, on a Bi2Te3
                      substrate. From angle-resolved photoemission spectroscopy
                      measurements and ab initio calculations, the electronic
                      structure of the system can be understood as an overlap of
                      the band dispersions of bilayer Bi and Bi2Te3. Our results
                      show that the Dirac cone is actually robust against
                      nonmagnetic perturbations and imply a unique situation where
                      the topologically protected one- and two-dimensional edge
                      states are coexisting at the surface.},
