Abstract. The relationship of energy
spectra of a molecule and transport charecteristics of single-electron
transistor based on this molecule is studied. Electron energy spectra of small
molecules of carboran C2B10H12, fullerene C60 and platinum molecular
cluster are calculated by means of quantum methods for their ground and exited
charge energy states. Effective capacitance parameters are established and
parametric approach for calculating electron levels in the molecule energy spectra
is proposed. Finally transport characteristics of the molecular single-electron
transistor are calculated by Monte-Carlo simulation.
Key words: molecular electronics,
single-electron transistor, electronic nanodevices, discrete energy spectra,
