摘要	We discover a pair of spin-polarized surface bands on the (111) face of grey arsenic by using angleresolved photoemission spectroscopy (ARPES). In the occupied side, the pair resembles typical nearlyfree- electron Shockley states observed on noble-metal surfaces. However, pump-probe ARPES reveals that the spin-polarized pair traverses the bulk band gap and that the crossing of the pair at (Gamma) over bar G is topologically unavoidable. First-principles calculations well reproduce the bands and their nontrivial topology; the calculations also support that the surface states are of Shockley type because they arise from a band inversion caused by crystal field. The results provide compelling evidence that topological Shockley states are realized on As(111).; We discover a pair of spin-polarized surface bands on the (111) face of grey arsenic by using angleresolved photoemission spectroscopy (ARPES).
