Identification of a surface state of the (111) terraces of stepped Cu(211)
Journal Article

· Phys. Rev. Lett.; (United States)
The surface electronic structure of a stepped Cu(211) crystal was elucidated by angle-resolved photoemission spectroscopy. A surface state was found on the three-atom terraces, indicating that the terrace surface potential resembles that of a Cu(111) crystal surface. The d-band dispersion relations of Cu(211) were also found to resemble bulk copper closely. The observed enhanced reactivity of the stepped surface does not appear to arise from gross changes in the surface electronic structure.
