摘要：

Slab calculations of the surface electronic structure of Rh(001) predict surface states. However, they disagree on their relative strengths and, in particular, whether the surface states near the point are located above or below the Fermi level. This has ramifications as regards the value of the surface charge density in relation to the magnitude of the work function values. We present angle-resolved photoemission evidence for a strong narrow spectral peak located just below EF about the point which is independent of photon energy, indicative of an occupied surface state, in agreement with one of the calculations. © 1990 IOP Publishing Ltd.
