Аннотация:
The physical nature of the aqueous tunnel barrier in a STM experiment is examined and the important role of spontaneous solvent dipole fluctuations, in providing microscopic trapping sites for electrons, is emphasized. Atomic resolution STM images of Au(111) surfaces in organic polar solvents are presented, which reveal detailed structural information on both the metallic substrate and the surface reconstruction.
