Abstract

The authors report on a detailed study of single crystal surfaces with (111) and (100) orientations by photoemission spectroscopy (PES). The surfaces were prepd. by sputtering, annealing, and post-oxidizing and characterized using LEED, XPS, and STM. The surface electronic structure turns out to be strongly dependent on the surface orientation and prepn. conditions. This also holds for more bulk sensitive PES measurements using photons with an energy at the Fe 2p resonance threshold. Thus the surface region extends much deeper into the bulk than the topmost at. layer. [on SciFinder (R)]
