Summary:
Nonlinearity is a factor role in electronic circuit which realize a various functions including oscillation, amplification, frequency conversion, etc. Considering conduction through molecules, electron tunneling gives simple ohmic character. The expression of nonlinearity in molecular systems requires Coulomb repulsion and/or weakly coupled discrete energy levels in conduction paths. In search of nonlinear electric properties, we investigated electronic properties of polyoxometalate (POM), cytochorome c, and cytochrome c/DNA networks. In these nano-molecular systems, nonlinear current-voltage characteristics are observed.
