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.},
