The growth mode and electronic structures of Fe thin films, epitaxially grown on Rh(001), were studied by various photoemission measurements for the film 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 structure of the Fe film resembles that of fcc(001) in the low coverage region and that of bcc(110) in the high coverage region. This transformation of the electronic structure is considered to be related to the thickness dependence of the interlayer spacing of the films.
