“…Since the crystal has 7 % nitrogen vacancies, vacancy-induced structures could be expected to appear. A vacancy-induced peak has earlier [16] been observed at about -2.1 eV on a substoichiometric ZrN(100) crystal. It showed no dispersion with photon energy and a "A,-like" symmetry behaviour.…”

“…[23] and T i c [24] and maybe at the photon energies used this is an intrinsic property of the (110) surface for these compounds. For the ZrN(100) surface on the other hand it has been found [16] that direct transitions give the dominant contribution to the photocurrent in recorded spectra and that the final state bands can be well approximated by freeelectron bands. Peak C cannot be explained by the theoretical band structure.…”

spectra for TMCN's of various compositions show that vacancy-induced peaks could show up in the spectra from substoichiometric ARPES investigation of a (100) crystal [16] clearly showed a vacancy-induced peak in normal emission spectra recorded at photon energies in the range 30-58 eV. Earlier angle-integrated An angle-resolved photoemission study of a ZrNo,93(l 10) single crystal is reported. Off-normal spectra recorded using unpolarized Ne I and He I resonance radiation are presented and the determined experimental peak dispersion are compraed with possible direct transitions calculated for zrN1.0. The results show that dominant emission Peaks at these Photon energies probably are one-dimensional density of states features, i.e., peaks originating from band extrema. A peak observed at about 2eV below the Fermi energy is interpreted as originating from occupied vacancy states.For ZrN, a recent photoemission experiments [ 17-19] on polycrystalline ZrN showed the existence Of a vacancy-induced peak*
