Fingerprinting the Electronic Wavefunctions of Ultra-Small Conductors

摘要

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