While the massless surface state is non-degenerate, chiral and insensitive to the interface potential, the massive surface states only appear for a sufficiently smooth heterojunction. The surface states are particle-hole symmetric and a voltage drop reveals their intrinsic relativistic nature, similarly to Landau bands of Dirac electrons in a magnetic field. We discuss the relevance of the massive Dirac surface states in recent ARPES and transp","authors_text":"A. Inhofer, B. Pla\\c{c}ais, D. Carpentier, E. Bocquillon, M. O. Goerbig, S. Tchoumakov, V.
