| Abstract: | Two dimensional (2-D) Au clusters were deposited on the self-assembled alkylthiol monolayer (SAM) by thermal evaporation and their I-V characteristics were studied by STM/STS. The curves show current steps similar to Coulomb blockade and the Coulomb staircase effect with asymmetric behavior. While the zero conductance gap is due to Coulomb blockade, in good agreement with semi-classical theory, the step-plateau behavior with asymmetry in voltage spacing and current increase can be attributed to the effect from internal energy levels. |
