Surface-sensitive Fe 2 p photoemission spectra for α- Fe 2 O 3 ( 0001 ) : The influence of symmetry and crystal-field strength

Abstract

We have measured high-energy-resolution Fe 2 p photoelectron spectra for α - Fe 2 O 3 / α - Al 2 O 3 ( 0001 ) grown by oxygen-plasma-assisted molecular-beam epitaxy at emission angles chosen to enhance bulk and surface contributions. We quantitatively reproduce the subtle line-shape differences in these spectra by taking into account the break in symmetry and change in crystal field splitting generated by the presence of the surface.
