Interface Dipole and STS comparisons

  1. Jan 11, 2016 #1
    Hi again people!

    So if I have two STS (scanning tunneling spectroscopy) spectra, one taken on a substrate and the other one taken on an adsorbate layer ontop of the substrate. Assuming there is some sort of interfacial dipole that forms between the substrate and the adsorbate layer, can I compare peak positions directly between the two spectra?

    i.e. This peak is the LUMO of adsorbate and this other peak is the CBM of the substrate
