These and other ,ponconventional" questions are discussed in this short overview, covering ideas, the main difficulties in their realization, and the first experimental examples. 1 Introduction Imaging the landscapes of solid surfaces ex-situ and in-situ is nowadays an established method for gaining information about their local structure. Reliable data about the structure of adsorbate overlayers on top of the substrate can also be obtained by this technique (see other papers in this volume), if the atoms are strongly adsorbed.

Focus has been on (a) solvent polarization effects on the metallic electronic structure [58, 591; (b) local pseudopotentials [59]; (c) electron tunnel routes through networks of ,,quantum dots" [60]; (d) time correlation effects and noise [60]; (e) resonance tunneling [62, 631, and ( f ) tunneling through intermediate local molecular levels as in other three-level coherent thermal and optical processes [56,57,64]. We discuss briefly the latter view. The intermediate state is representative of the metal centers in metalloproteins or large transition-metal complexes, spatially separated fiom the electrodes by protein or intramolecular ligand frames.

The difference is in the values of coefficients in these expressions. 3 How and where to use these formulas The analytical results, presented above, are valid for the diffusion of adatoms independently moving along the flat substrate surface. At a ftrst glance, the account for the lattice structure of the surface could significantly change the resulting equations. , the tip is not too sharp. Substituting the flat surface for the lattice is then somewhat similar to substituting the integral for the sum when there are many terms with a slow dependence on their number.
