Fig. 16.7 (continues) Panels (d–h) are results from varying the ImV(z) parameters that determines
the absolute intensity (wave function amplitude). The similar quantitative effect of γ and η on the
intensity indicates that the topmost layer (z ≤ z SL ) dominates the process of damping. Electrons
from below the substrate second plane give no contribution, evidencing that the VLEED collects
information from the top single atomic layer. (Reprinted with permission from [13, 14])
