摘要：

We measured the inverse-photoemission spectra (IPES) of iron oxides grown on an Fe substrate and calculated the band structure of paramagnetic FeO to analyze the IPES. The band-structure calculation showed some overlap between Fe 3d states and O 2p states in the region of occupied states, and s,p-like states of Fe in the unoccupied region. Isochromatic IPES showed two structures at 2.5 and 7.5 eV above the Fermi energy. We estimated from the IPES data a full band gap of 2.5 eV for FeO. © 1990 The American Physical Society.
