Abstract
We present a theoretical study of the influence of localized d states from a transition metal surface on the tunneling spectra obtained by scanning tu nneling spectroscopy (STS). This problem is considered here for the system formed by a Ni(0 0 1) surface and an Al or Ni tip. It is found, that the d band of a Ni(0 0 1) substrate could considerably modify the STS tunneling s pectra, but only for very small (around 2.5 Angstrom) tip-sample distances. The obtained results also show that the d band features in STS spectra dep end strongly on the properties of the STM tip. (C) 1999 Published by Elsevi er Science Ltd. All rights reserved.
