Comment:

NbN(100)-(1x1). The sample was cleaned by cycles of Ar+ ion bombardment and flashings (T= ~1273 K) in N2 atmosphere (p = 1E-4 torr). The spectra were recorded at normal emission. Asymmetry parameter = 0.06. The Gaussian FWHM was varied from 0.47 eV at 435 eV photon energy to 0.55 eV at 520 eV.
