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, stability diagram.
