Effect of interactions and degeneracy on transmission through a single molecule
ORAL
Abstract
Electron transmission through a single-molecule junction in the Coulomb blockade regime is analyzed in the isolated resonance approximation for molecules with degenerate HOMO and/or LUMO orbitals. Electron-electron interactions are included in a capacitive charging model derived from pi-electron effective field theory. For the case of a buckyball junction with Pt electrodes, we find that the number of transmission channels is limited by the five-fold degenerate HOMO resonance.
