Abstract
We present the Schottky-barrier height determination for the Fe/ZnSe(001) system performed by core and valence level photoelectron emission spectroscopy. Above the thickness of 2 ML, the Fe–Fermi level position is stabilized at 1.6 eV above the valence-band maximum of the n-type undoped ZnSe. This corresponds to a Schottky-barrier height value of 1.1 eV. A bulk-like d-band electronic structure could be observed for thickness as thin as 2 ML of Fe.
