Scholarcy highlights

  • A combination of classical Coulomb charging, electronic level spacings, spin, and vibrational modes determines the single-electron transfer reactions through nanoscale systems connected to external electrodes by tunnelling barriers1
  • We describe a single-electron transistor where the electronic levels of a single π-conjugated molecule in several distinct charged states control the transport properties
  • We suggest, and verify by simple model calculations, that this surprising effect could be caused by image charges generated in the source and drain electrodes resulting in a strong localization of the charges on the molecule
  • J.C. is a research fellow of the FNRS
