Single Electron Transport of Oligothiophene molecules

POSTER

Abstract

We examined the fabrication of single-electorn transistors (SETs) with oligothiophene derivative or Au nano particle covered with oligothiophene as Coulomb island. The SET device was consisted of a nanogap electrode, a molecular Coulomb island, and back gate electrode. The nanogap electrode was fabricated by the electromigration method. We could obtain the SET characteristics from the electron transport properties of both devices at 11K. Spectra that owing to a molecule was obtained in the electric transport properties of these devices. Moreover, we could obtain the SET characteristics in some devices.
