    • Large (formula presented) (outside the range ±1 V) causes abrupt, hysteretic changes in the scattering, likely due to rearrangement of charges in the donor or surface layers (Ref. Charges in these layers also cause the contact potential, at which the tip does not perturb the sample, to vary from 0–0.3 V at different locations

    • Impurities located on opposite sides of the incompressible strip should cause scattering similar to Fig. 55 but at opposite (formula presented) polarity (this is also true for bound states having energies on opposite sides of the Fermi level). We believe this is the origin of the dark spots of reduced scattering at positive (formula presented) in Fig. 22. It also explains why such dark spots occur with the same frequency as the rings of increased scattering
