Evidence for a surface resonance feature in the very low-energy electron spectrum of ZrN

Previous investigations of the low-energy (0-40 eV) electron spectra of Ti and V nitrides have been extended to ZrN. The lowenergy spectra of ZrN films prepared by nitrogen ion implantation contain the corresponding features to those previously observed for TiN and VN. However, the ZrN spectrum is dominated by an extremely large feature at about 3 eV, which has not been previously reported. The amplitude of this peak varies directly with the …
