FIGURE 3.14Using STM to understand the chemistry of surfaces

STM images of the Si(111) 7 × 7 surface reconstruction showing the spatial location of different electronic orbitals associated with different surface and near-surface atoms. The images depict the adatom states at (a) −0.35 eV, (b) −0.8 eV, and (c) −1.7 eV relative to the Fermi energy.
