Description
By extending the Orthodox theory of Coulomb blockade to include the nano-scale effects of environmental electric fields, we show that tunneling spectra of metallic nanoislands contain information not only on the energies of the electronic levels but also on their wavefunctions near the surface of the island. This fundamental additional information is predicted to take the form of new observable phenomena that are beyond the scope of the standard Orthodox theory: the tunneling resonances are renormalized and show nearly-Gaussian fluctuations, level bending and avoided crossings.
