摘要：

Beyond single molecule electronics, exploration of device architecture is a central issue in molecular-scale electronics. We have demonstrated that the cytochrome c (Cyt c) network array acts as an electronic circuit that consists of a redox element. The current voltage characteristics of the Cyt c network array reveal nonlinear curves with a threshold voltage (V-th) that corresponds well with the Coulomb blockade (CB) model over a wide range of temperature. As an indication of the threshold behavior, a weak periodic input signal is optimized by the presence of a particular level of noise that enhances signal detection. This result indicates that stochastic resonance (SR) emerges in the Cyt c redox network array.
