Growth of Fe films on Rh(001): a photoemission study

The growth mode and electronic structures of Fe thin films, epitaxially gro wn on Rh(001), were studied by various photoemission measurements for the f ilm thickness of 0-12 monolayers. By comparing the valence band structures obtained from the angle-resolved photoemission spectra and the theoretical band calculations for the bulk Fe, we concluded that the valence band struc ture of the Fe film resembles that of fcc(001) in the low coverage region a nd that of bcc(110) in the high coverage region. This transformation of the electronic structure is considered to be related to the thickness dependen ce of the interlayer spacing of the films. (C) 2001 Elsevier Science B.V. A ll rights reserved.
