Abstract
The valence band structure of a HfN0.93 (100) crystal has been investigated utilizing angle-resolved photoemission and HeI, NeI and ArI radiation. The experimental data are compared with calculated spectra and calculated direct transitions for stoichiometric HfN. The comparison shows that most of the structures in the recorded spectra can be identified as originating from bulk band transitions. The dispersions of the experimental peaks are predicted reasonably well theoretically, using final states approximated by free-electron bands. However, the experimental peaks are in general found somewhat deeper below the Fermi level than the calculated positions.
